Question

factorize using identities :- 9x²-144​

Answer 1

Answer:

After factorizing we will get $(3x-12)(3x+12)$

Step-by-step explanation:

The given expression is 9x²-144​

We can solve this by the identity $a^{2} - b^{2} = (a+b)(a-b)$

If we use a =3x and b = 12

We will get

$9x^2-144\\(3x)^{2} -12^{2} \\(3x-12)(3x+12)$
