Weegy: (x^2 - 4)(x - y)(x + y). -x2y2 + x4 + 4y2 - 4x2 can be factorized as (x^2 - 4)(x - y)(x + y). Source:

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

5!/3! = 20

5! = 5 * 4 * 3 * 2 * 1 = 120;
3! = 3 * 2 * 1 = 6;

120/6 = 20

7!/5! * 2! = 84

7!= 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5,040;
5! = 5 * 4 * 3 * 2 * 1 = 120;
2! = 2 * 1 = 2;

5,040/120 * 2 = 84
