(i) (x + 1)2 = 2(x – 3) We have: (x + 1)2 = 2 (x – 3) x2 + 2x + 1 = 2x – 6 ⇒ x2 + 2x + 1 – 2x + 6 = 0 ⇒ x2 + 70 Since x2 + 7 is a quadratic POLYNOMIAL ∴ (x + 1)2 = 2(x – 3) is a quadratic equation. (ii) x2– 2x = (–2) (3 – x) We have: x2 – 2x = (– 2) (3 – x) ⇒ x2 – 2x = –6 + 2x ⇒ x2 – 2x – 2x + 6 = 0 ⇒ x2 – 4x + 6 = 0 Since x2 – 4x + 6 is a quadratic polynomial ∴ x2 – 2x = (–2) (3 – x) is a quadratic equation. (iii) (x – 2) (x + 1) = (x – 1) (x + 3) We have: (x – 2) (x + 1) = (x – 1) (x + 3) ⇒ x2 – x – 2 = x2 + 2x – 3 ⇒ x2 – x – 2 – x2 – 2x + 3 = 0 ⇒ –3x + 1 = 0 Since –3x + 1 is a linear polynomial ∴ (x – 2) (x + 1) = (x – 1) (x + 3) is not quadratic equation. (iv) (x – 3) (2x + 1) = x(x + 5) We have: (x – 3) (2x + 1) = x(x + 5) ⇒ 2x2 + x – 6x – 3 = x2 + 5x ⇒ 2x2 – 5x – 3 – x2 – 5x – 0 ⇒ x2 + 10x – 3 = 0 Since x2 + 10x – 3 is a quadratic polynomial ∴ (x – 3) (2x + 1) = x(x + 5) is a quadratic equation. (v) (2x – 1) (x – 3) = (x + 5) (x – 1) We have: (2x – 1) (x – 3) = (x + 5) (x – 1) ⇒ 2x2 – 6x – x + 3 = x2 – x + 5x – 5 ⇒ 2x2 – x2 – 6x – x + x – 5x + 3 + 5 = 0 ⇒ x2 – 11X + 8 = 0 Since x2 – 11x + 8 is a quadratic polynomial ∴ (2x – 1) (x – 3) = (x + 5) (x – 1) is a quadratic equation. (vi) x2 + 3x + 1 = (x – 2)2 We have: x2 + 3x + 1 = (x – 2)2 ⇒ x2 + 3x + 1 = x2 – 4x + 4 ⇒ x2 + 3x + 1 – x2 + 4x – 4 =0 ⇒ 7x – 3 = 0 Since 7x – 3 is a linear polynomial. ∴ x2 + 3x + 1 = (x – 2)2 is not a quadratic equation. (vii) (x + 2)3 = 2x(x2 – 1) We have: (x + 2)3 = 2x(x2 – 1) x3 + 3x2(2) + 3x(2)2 + (2)3 = 2x3 – 2x ⇒ x3 + 6x2 + 12x + 8 = 2x3 – 2x ⇒ x3 + 6x2 + 12x + 8 – 2x3 + 2x = 0 ⇒ –x3 + 6x2 + 14x + 8 = 0 Since –x3 + 6x2 + 14x + 8 is a polynomial of degree 3 ∴ (x + 2)3 = 2x(x2 – 1) is not a quadratic equation. (viii) x3 – 4x2 – x + 1 = (x – 2)3 We have: x3 – 4x2 – x + 1 = (x – 2)3 ⇒ x3 – 4x2 – x + 1 = x3 + 3x2(– 2) + 3x(– 2)2 + (– 2)3 ⇒ x3 – 4x2 – x + 1 = x3 – 6x2 + 12x – 8 ⇒ x3 – 4x2 – x – 1 – x3 + 6x2 – 12x + 8 = 0 2x2 – 13x + 9 = 0 Since 2x2 – 13x + 9 is a quadratic polynomial ∴ x3 – 4x2 – x + 1 = (x – 2)3 is a quadratic equation.

1.

Find the following linear equations by factorisation 2*2+x-4=0

Answer»

ong>Answer:

(i) (x + 1)2 = 2(x – 3)

(ii) x2 – 2x = (–2)(3 – x)

(III) (x – 2)(x + 1) = (x – 1)(x + 3)

(iv) (x – 3)(2x + 1) = x(x + 5)

(v) (2x – 1) (x – 3) – (x + 5) (x – 1)

(vi) x2 + 3x +1 = (x – 2)2

(vii) (x + 2)3 = 2x(x2 – 1)

(viii) x3 – 4x2 – × + 1 = (x – 2)3

Sol. (i) (x + 1)2 = 2(x – 3)

We have:

(x + 1)2 = 2 (x – 3) x2 + 2x + 1 = 2x – 6

⇒ x2 + 2x + 1 – 2x + 6 = 0

⇒ x2 + 70

Since x2 + 7 is a quadratic POLYNOMIAL

∴ (x + 1)2 = 2(x – 3) is a quadratic equation.

(ii) x2– 2x = (–2) (3 – x)

We have:

x2 – 2x = (– 2) (3 – x)

⇒ x2 – 2x = –6 + 2x

⇒ x2 – 2x – 2x + 6 = 0

⇒ x2 – 4x + 6 = 0

Since x2 – 4x + 6 is a quadratic polynomial

∴ x2 – 2x = (–2) (3 – x) is a quadratic equation.

(iii) (x – 2) (x + 1) = (x – 1) (x + 3)

We have:

(x – 2) (x + 1) = (x – 1) (x + 3)

⇒ x2 – x – 2 = x2 + 2x – 3

⇒ x2 – x – 2 – x2 – 2x + 3 = 0

⇒ –3x + 1 = 0

Since –3x + 1 is a linear polynomial

∴ (x – 2) (x + 1) = (x – 1) (x + 3) is not quadratic equation.

(iv) (x – 3) (2x + 1) = x(x + 5)

We have:

(x – 3) (2x + 1) = x(x + 5)

⇒ 2x2 + x – 6x – 3 = x2 + 5x

⇒ 2x2 – 5x – 3 – x2 – 5x – 0

⇒ x2 + 10x – 3 = 0

Since x2 + 10x – 3 is a quadratic polynomial

∴ (x – 3) (2x + 1) = x(x + 5) is a quadratic equation.

(v) (2x – 1) (x – 3) = (x + 5) (x – 1)

We have:

(2x – 1) (x – 3) = (x + 5) (x – 1)

⇒ 2x2 – 6x – x + 3 = x2 – x + 5x – 5

⇒ 2x2 – x2 – 6x – x + x – 5x + 3 + 5 = 0

⇒ x2 – 11X + 8 = 0

Since x2 – 11x + 8 is a quadratic polynomial

∴ (2x – 1) (x – 3) = (x + 5) (x – 1) is a quadratic equation.

(vi) x2 + 3x + 1 = (x – 2)2

We have:

x2 + 3x + 1 = (x – 2)2

⇒ x2 + 3x + 1 = x2 – 4x + 4

⇒ x2 + 3x + 1 – x2 + 4x – 4 =0

⇒ 7x – 3 = 0

Since 7x – 3 is a linear polynomial.

∴ x2 + 3x + 1 = (x – 2)2 is not a quadratic equation.

(vii) (x + 2)3 = 2x(x2 – 1)

We have:

(x + 2)3 = 2x(x2 – 1)

x3 + 3x2(2) + 3x(2)2 + (2)3 = 2x3 – 2x

⇒ x3 + 6x2 + 12x + 8 = 2x3 – 2x

⇒ x3 + 6x2 + 12x + 8 – 2x3 + 2x = 0

⇒ –x3 + 6x2 + 14x + 8 = 0

Since –x3 + 6x2 + 14x + 8 is a polynomial of degree 3

∴ (x + 2)3 = 2x(x2 – 1) is not a quadratic equation.

(viii) x3 – 4x2 – x + 1 = (x – 2)3

We have:

x3 – 4x2 – x + 1 = (x – 2)3

⇒ x3 – 4x2 – x + 1 = x3 + 3x2(– 2) + 3x(– 2)2 + (– 2)3

⇒ x3 – 4x2 – x + 1 = x3 – 6x2 + 12x – 8

⇒ x3 – 4x2 – x – 1 – x3 + 6x2 – 12x + 8 = 0

2x2 – 13x + 9 = 0

Since 2x2 – 13x + 9 is a quadratic polynomial

∴ x3 – 4x2 – x + 1 = (x – 2)3 is a quadratic equation.

4.	Prove the following as irrational numbr √3/5
Answer» ONG>ANSWER: Step-by-step explanation: HI friend!! Let √3/5 be a rational NUMBER. A rational number can be written in the form of p/q where p,q are integers. √3/5 = p/q √3 = p/q-√5 Squaring on both sides, (√3)² = (p/q-√5)² 3 = p²/q²+√5²-2(p/q)(√5) √5×2p/q = p²/q²+5-3 √5 = (p²+2q²)/q² × q/2p √5 = (p²+2q²)/2pq p,q are integers then (p²+2q²)/2pq is a rational number. Then √5 is also a rational number. But this CONTRADICTS the fact that √5 is an irrational number. So,our supposition is false. Therefore, √3/5 is an irrational number.

4.

Prove the following as irrational numbr √3/5

Answer» ONG>ANSWER:

Step-by-step explanation:

HI friend!!

Let √3/5 be a rational NUMBER.

A rational number can be written in the form of p/q where p,q are integers.

√3/5 = p/q

√3 = p/q-√5

Squaring on both sides,

(√3)² = (p/q-√5)²

3 = p²/q²+√5²-2(p/q)(√5)

√5×2p/q = p²/q²+5-3

√5 = (p²+2q²)/q² × q/2p

√5 = (p²+2q²)/2pq

p,q are integers then (p²+2q²)/2pq is a rational number.

Then √5 is also a rational number.

But this CONTRADICTS the fact that √5 is an irrational number.

So,our supposition is false.

Therefore, √3/5 is an irrational number.

11.	A triangular colourful scenery is made on a wall with sides 25cm, 25cm and 40cm. A golden thread is to hang from the vertex so as to just reach the side 40cm perpendicularly. How much length of the golden thread is required? *
Answer» ong>Solution :- Given that, sides of TRIANGULAR colourful scenery are 25cm, 25cm and 40cm. As we can SEE two sides are 25cm each . Therefore, we can conclude that, the scenery is in the shape of a Isosceles TRIANGLE with two sides as 25cm and base as 40cm. Now, we know that, Perpendicular on base of a isosceles triangle bisect the base into two equal parts. So, By pythagoras theorem we get, → (Perpendicular)² + (Base/2)² = (Equal side)² Putting value as Base = 40cm and Equal side as 25cm , we get, → (Perpendicular)² + (40/2)² = (25)² → (Perpendicular)² + (20)² = (25)² → (Perpendicular)² + 400 = 625 → (Perpendicular)² = 625 - 400 → (Perpendicular)² = 225 → (Perpendicular)² = (15)² Square - root both sides now, we get, → Perpendicular = 15 cm. (Ans.) Hence, length of the golden thread is 15cm.

ong>Solution :-

Given that, sides of TRIANGULAR colourful scenery are 25cm, 25cm and 40cm.

As we can SEE two sides are 25cm each . Therefore, we can conclude that, the scenery is in the shape of a Isosceles TRIANGLE with two sides as 25cm and base as 40cm.

Now, we know that, Perpendicular on base of a isosceles triangle bisect the base into two equal parts.

So, By pythagoras theorem we get,

→ (Perpendicular)² + (Base/2)² = (Equal side)²

Putting value as Base = 40cm and Equal side as 25cm , we get,

→ (Perpendicular)² + (40/2)² = (25)²

→ (Perpendicular)² + (20)² = (25)²

→ (Perpendicular)² + 400 = 625

→ (Perpendicular)² = 625 - 400

→ (Perpendicular)² = 225

→ (Perpendicular)² = (15)²

Square - root both sides now, we get,

→ Perpendicular = 15 cm. (Ans.)

Hence, length of the golden thread is 15cm.

What is the answer of 3x +6y ×7s *+81

Answer» ONG>Answer:

Simplifying

3x + 6Y = 81

Solving

3x + 6y = 81

Solving for variable 'x'.

Move all TERMS containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

3x + 6y + -6y = 81 + -6y

Combine like terms: 6y + -6y = 0

3x + 0 = 81 + -6y

3x = 81 + -6y

Divide each side by '3'.

x = 27 + -2y
