Question

factors of 4xsquare-9ysquare

Answer 1

(2x + 3y) • (2x - 3y)

Answer 2

Hi there !!


Given,
to factorise

$4x {}^{2} - 9y {}^{2}$
The following expression is in the form of the identity a^2-b^2 = (a-b)(a+b)
where,

a = 2x , since (2x)^2=4x^2
b = 3y , since (3y)^2 = 9y^2

So,

( 2x - 3y)(2x + 3y ) is the answer
