Question

Factorisation of 9xsquare - 16ysquare

Answer 1

Answer:

$(3x + 4y)(3x - 4y)$

Step-by-step explanation:

${9x}^{2} - {16y}^{2}$

By, using an identity :-

${a}^{2} - {b}^{2} = (a + b)(a - b)$

We, get,

${9x}^{2} - {16y}^{2} = (3x + 4y)(3x - 4y)$

So,

Factorisation of 9x² and 16y² = (3x+4y)(3x-4y)

Please mark my answer as the BRAINLIEST answer.

Answer 2

Answer:

(3x+y)(3x-y)

this is the answer of this question
