Question

The factors of (x)² + 9x -36 are​

Answer 1

Answer:

x²+9x-36

x²+12x-3x-36

x(x+12) -3(x+12)

(x+12) (x-3)

Answer 2

CONCEPT:-

• Break the middle term and make it for the multiplication of coeff. of x and constant 'c'.
• To make it simple, we can solve it by 3 methods till class 10th and class12 th is considered,but we will solve it by easist way l, BTMT method.

ANSWER:-

(x-3)and (x+12).....

STEP BY STEP EXPLAINATION:-

$equation \: is.$

${x}^{2} + 9x - 36$

Breaking the middle term.

=> x²+12x-3x-36=0

=>x(x-12)-3(x-12)=0

=>(x-3)(x-12)=0---------> Required answer

But lets solve it further.

Now,

equating them both by zero will get us,the final values.

x-3=0,x-12=0

=>x=3 and x=12
