Weegy: (-4 + x^2) (x^2 - y^2). Please rate the answer.
User: Factor 3x2 - 15x - 42.
3(x - 2)(x - 7)
3(x - 2)(x + 7)
3(x - 7)(x + 2)
Weegy: 4. 3(x - 7)(x + 2) is the answer. 3x^2 - 15x - 42 = 3(x - 7)(x + 2)

-x^2y^2 + x^4 + 9y^2 - 9x^2
= x^2(x^2 - y^2) - 9(x^2 - y^2)
= (x^2 - y^2)(x^2 - 9)
= (x + y)(x - y)(x + 3)(x - 3)
