Answer» The given equation is » kx² - 14x + 8 = 0 Divide the equation THROUGHOUT by K. » x² - 14x/k + 8/k = 0 Let the two roots be A and 6A. According to the given condition. Sum of roots = -b/a => A + 6A = 14/k » 7A = 14/k » A = 2/k ... (1) PRODUCT of the roots = c/a => A × 6A = 8/k => 6A² = 8/k ... (2) Substitute (1) in (2) » 6 (2/k)² = 8/k » 6/k² = 8/k » k = 3/4 Substitute in eq (1) A = 2/k = (3/4) / 2 = 3/8 6A = 9/4 Therefore, roots are 3/8 and 9/4.

1. Find the roots of the quadratic equationFind the value of k, for which one root of the quadratic equation kx2 - 14x + 8 is six timesthe other

Answer»

The given equation is

» kx² - 14x + 8 = 0

Divide the equation THROUGHOUT by K.

» x² - 14x/k + 8/k = 0

Let the two roots be A and 6A.

According to the given condition.

Sum of roots = -b/a

=> A + 6A = 14/k

» 7A = 14/k

» A = 2/k ... (1)

PRODUCT of the roots = c/a

=> A × 6A = 8/k

=> 6A² = 8/k ... (2)

Substitute (1) in (2)

» 6 (2/k)² = 8/k

» 6/k² = 8/k

» k = 3/4

Substitute in eq (1)

A = 2/k = (3/4) / 2 = 3/8

6A = 9/4

Therefore, roots are 3/8 and 9/4.

Answer» This QUESTION can be solved by using concept of Arithmetic Progression ( AP ). Now, the first EVEN number between 1 to 150 = 2 So, a1 = 2 Last even number between 1 to 150 = 150 So an, = 150 COMMON difference ( d ) = second term - first term = 4 - 2 = 2 We know that an = a+ ( n - 1 ) 150 = 2+(n - 1 )× 2 150 - 2 = ( n - 1 ) × 2 148 = ( n - 1 ) × 2 148 / 2 = n - 1 74 = n - 1 74 + 1 = n 75 = n We know that , SN = n upon 2 ( a + an ) = 75 upon 2 ( 2 + 150 ) = 75 upon 2 × 152 = 75 upon 2 × 152 75 × 76 = 5700 So, sum of all even number between 1 + 150 is 5700.

12.

Find out sum of all even number in between 1 to 151

Answer»

This QUESTION can be solved by using concept of Arithmetic Progression ( AP ).

Now, the first EVEN number between 1 to 150 = 2

So, a1 = 2

Last even number between 1 to 150 = 150

So an, = 150

COMMON difference ( d ) = second term - first term

= 4 - 2

= 2

We know that an = a+ ( n - 1 )

150 = 2+(n - 1 )× 2

150 - 2 = ( n - 1 ) × 2

148 = ( n - 1 ) × 2

148 / 2 = n - 1

74 = n - 1

74 + 1 = n

75 = n

We know that ,

SN = n upon 2 ( a + an )

= 75 upon 2 ( 2 + 150 )

= 75 upon 2 × 152

75 × 76

= 5700

So, sum of all even number between 1 + 150 is 5700.

Answer»

SOLUTION

TO DETERMINE

If ‘x’ is a counting number

(a) The number should be added to x² + 6x to become a perfect square

(b) The value of a if x² + ax +16 is a perfect square

EVALUATION

(a)

$\sf{ {x}^{2} + 6x }$

$\sf{ = {x}^{2} + 2.x.3 + {(3)}^{2} - {(3)}^{2} }$

$\sf{ = {(x + 3)}^{2} - 9}$

The number should be added = 9

(b)

$\sf{ {x}^{2} + ax + 16}$

$\sf{ = {x}^{2} \pm 2.x.4 + {(4)}^{2} \mp \: 2.x.4 + ax }$

$\sf{ = {(x \pm 4)}^{2} + x(a \mp 8)}$

Hence the REQUIRED value

$\sf{a = \pm 8}$

49.	What are the roots of quadratic equation x²=9?
Answer» Answer: One WAY to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one SIDE equal to 0: x2 – 9 = 0. The expression on the left can be factored: (x + 3)(x – 3) = 0. Using the zero factor property, you KNOW this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3
