12x2-50x-18=0 what is the factored form

Answer»

Answer:

the VALUES are : 9/2 &-1/3.

Step-by-step explanation:

12x^2-50x-18=0

2(6x^2-25x-9)=0

6x^2-25x-9=0

                                                                                                              -54 = -27,+2

6x^2+2x-27x-9=0

2x(3x+1)-9(3x+1)=0

(2x-9)(3x+1)=0

2x-9=0 , 3x+1=0

2x=9 , 3x=-1

x=9/2,-1/3

         THEREFORE,

                                   x=9/2,-1/3

A farmer requires four bags of fertilizer and three packets of maize seed for his plot.the total cost for both is sh 1 500.if a bag of fertilizer costs sh 200 more than a packet of maize seed,calculate the price of a) a bag of fertilizer b) a packet of maize seed

Answer»

Answer:

Let cost of 1 PACKET of maize SEEDS = x

Let cost of 1 BAG of fertilizer = x+200

3x +4(x+200)=1500

3x+4x+800=1500

7x=1500-800

7x=700

x=700÷7

x=100

Cost of 1 packet of maize seeds=x =100

Cost of 1 bag of fertilizer =x+200

=100+200

=300

Step-by-step explanation:

Let the consumption of sugar ORIGINALLY be 1 unit and let its cost be Rs 100.

Then, the new cost will be Rs125.

Now, Rs 125 will yeild ( 1/125 × 100 ) unit= 4/5 unit of sugar.

Then, reduction in consumption = ( 1 - 4/5 ) = 1/5 unit

Therefore, reduction % in consumption = ( 1/5 × 100 )%

= 20 %

Form a quadratic polynomial one of whose zero is√5and the product of the zeros is -2√5​

Answer»

ANSWER:

  • Required polynomial = x²-(√5-2)x-2√5

GIVEN:

  • FIRST zero (α) = √5.
  • Product of ZEROS (αβ) = -2√5.

TO FIND:

  • A quadratic polynomial.

SOLUTION:

=> First zero (α) = √5.

Finding second zero (β)

=> Product of zeros (αβ) = -2√5

=> (√5)*(β) = -2√5

=> β = -2√5/√5

=> β = -2

Sum of zeros (α+β):

= √5+(-2)

= √5-2

Standard FORM of Quadratic polynomial when Zeros are given:

= x²-(α+β)x+αβ. ....(i)

PUTTING the values in eq (i)

= x²-(√5-2)x+(-2√5)

= x²-(√5-2)x-2√5

NOTE:

Some important formulas:

=> Sum of zeros (α+β) = -(Coefficient of x)/Coefficient of x²

=> Product of zeros (αβ) = Constant term/ Coefficient of x²

(1)The breadth of a rectangle is 1.28 m and the length of the same is 72 cm more than its breadth. Find out the length of the rectangle in meters.(2)The perimeter of the above rectangle will be?(3) If Ahmed doubles the length and keeps the breadth same of the above rectangle, how much will be the area of the rectangle?

Answer»

Step-by-step explanation:

GIVEN:-

BREADTH is 1.28 m => 128 cm

Length is 72 cm more than Breadth

ie Length will be 128+72 = 200 cm.

LENGTH = 2metres.

PERIMETER:-

We KNOW that

Perimeter of Rectangle = 2(l +b )

Where l is length

and b is Breadth

P = 2( 200+128)

= 2× 328

PERIMETER = 656 centimetres = 6.56 metres.

When Length is doubled,

that means Length × 2

= 200× 2 = 400 cm is length,

Breadth is same

AREA=?

AREA= L× B

Where L is Length and B is breadth

So placing the values

AREA = 400× 128

AREA = 51200 centimetres

AREA = 512 Metres.

We can Split the MIDDLE Term of this expression to FACTORISE it and thereby find solutions.

In this TECHNIQUE, if we have to factorise an expression like  

ax2+bx+c

, we need to think of 2 numbers such that:

N1⋅N2=a⋅c=1⋅−12=−12

 ANDN1+N2=b=−1

After trying out a few numbers we get  

N1=3  and  N2=−4  3⋅−4=−12, and  3+(−4)=−1  x2−x−12=x2−4x+3x−12

x(x−4)+3(x−4)=0  

(x+3)(x−4)=0  

Now we EQUATE the factors to zero.

x+3=0,x=−3

x−4=0,x=4
