User: Factor the following polynomial completely. -x2y2 + x4 + 4y2 - 4x2

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)

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

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

Evaluate 3! + 4!.

Weegy: 4! = 4 x 3 x 2 x 1 = 24. [smile] User: Evaluate 3! Weegy: 3!... The factorial (!) of a positive integer n is the product of all positive integers less than or equal to n. 3*2*1... Multiply 3 by 2 to get 6. 6*1... Multiply 6 by 1 to get 6. 6 is the answer... (More)

3! + 4! = 30;

3! = 3 * 2 * 1 = 6;
4! = 4 * 3 * 2 * 1 = 24;

6 + 24 = 30
