Question

(3x - 2y)(3x + y)
$algebra division class 7$
​

Answer 1

Answer:

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

this is in the form of (a+b)(a-b) so its answer eill be in form of a²-b²

Step-by-step explanation:

(3x)²-(2y)²

Answer 2

Answer:

(x+a) (x-b) = x² + (a+b)x - ab

= (3x) ² + (2y+ y)3x - 2y * y

= 9x² + ( 3y) 3x - 2y²

= 9x² + 9xy - 2y²
