: this is the problem that i tryed to solve but got confused
4x2y2-4x2-9y2+9
4(x2y2-x2)-9(y2+9)
4x2(y2-1)-9(y2-1)
(4x2-9)(y2-1)
did i do this correctly or am i missing a step This question is from textbook Algebra Introductory and Intermediate

You can put this solution on YOUR website!
4x2y2-4x2-9y2+9
4x^2(y^2-1) -9(y^2-1)
(y^2-1)(4x^2-9)
You have it right up to this point
= (y-1)(y+1)(2x-3)(2x+3
