Evaluate x1 - x-1 + x0 for x = 2. **Weegy:** When x = 2,
x^1 - x^-1 + x^0
= 2^1 - 2^-1 + 2^0
= 2 - 1/2 + 1
= 5/2 or 2 1/2 (More)

Factor 4b 2 - 9.
(4b + 3)(b - 3)
(2b + 3)(2b - 3)
(2b - 4)(2b - 5) **Weegy:** 4b^2 - 9 = (2b + 3)(2b - 3) (More)

Factor the following polynomial completely.
-x 2 y 2 + x 4 + 4y 2 - 4x 2
(x - 2)(x - 2)(x + y)(x - y)
(x + 2)(x + 2)(x + y)(x - y)
(x + 2)(x - 2)(x + y)(x - y) **Weegy:** -x^2y^2 + x^4 + 4y^2 - 4x^2 = x^2(x^2 - y^2) + 4(y^2 - x^2) = (x^2 - y^2)(x^2 - 4) = (x - y)(x + y)(x - 2)(x + 2) (More)
