-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)

= -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)

Evaluate.
5!/3! **Weegy:** 5! = 5 x 4 x 3 x 2 x 1 = 120. [smile] **User:** Evaluate.
7!/5!2! **Weegy:** 4^2 X 2 + 7 =16*2+7 =32+7 =39 Using order of operations you will do the exponent first, then the multiplication and then the additon. (More)

5!/3! = 20

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

3! = 3 * 2 * 1 = 6;

120/6 = 20

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

3! = 3 * 2 * 1 = 6;

120/6 = 20
