"give the correct answer"​

Answer 1

Step-by-step explanation:

............I hope it will help you

Answer 2

i. 25 x²- 36

=> (5x)² - (6)²

We know that :-

a²-b² =( a+b)( a-b)

=> (5x - 6) (5x + 6)

ii. x²+9x+14

We will factorize this by using middle term splitting method.

Now,( 7x)× (2 x )= 14 x²

7x+ 2 x = 9 x

=> x²+7x+2x+14

=>x (x+7)+2(x+7)

taking out (x+7) as common :-

=> (x+7)(x+2)

Additional Information :-

why do we factorize ?

⏩We factorize to find out factors of a number. Any number can be presented or expressed in the form of its factor.

For example :-

1. Factors of 10 are 2 and 5.

Therefore , 10= 2×5

2. Factors of 3m are 3 and m.

Therefore , 3m = 3 × m
