Question

Factorise the following expression 49x²-36

Answer 1

Given,

The main term for factorization = 49x²-36

To find,

The simplified final result of the given main term for factorization.

Solution,

We can factorise the given term using the normal algebraic formula of factorization.

Here, we can apply the formula of (a²-b²) = (a+b) (a-b), to factorise the given term.

Factorization :

= 49x²-36

= (7x)² - (6)² [Here, 7x = a & 6 = b]

= (7x+6) (7x-6)

[This cannot be further simplified, so we can take this as the final result of the given factorization.]

Hence, the final result of factorization is (7x+6) (7x-6)

Answer 2

:-

= (7x²) - (6)²

= (7x + 6) (7x - 6)
