Question

factorization of 9x²-4y²
​

Answer 1

Answer:

Step-by-step explanation:

$9x^{2} - 4y^{2} \\\\(3x)^{2} - (2y)^{2}\\ : a^{2} - b^{2} = (a-b)(a+b)\\= (3x - 2y)(3x + 2y)$

Answer 2

Answer:

(3x+2y) ( 3x-2y)

Step-by-step explanation:

This comes when we factories 9x2 with (3x)2 and -4y2 with -(4y)2
