-28

If that's -5 the answer is (x - 5)(x + 1)

4x + 32 = 4(x + 8)

4x3 + 16x2 - 180x = 4x(x2 + 4x - 45) = 4x(x + 9)(x - 5)

f(x) = x2-4x-5 = x2-5x+x-5 = x(x-5)+1(x-5) = (x+1)(x-5) Factors of f(x) are (x+1) and (x-5).

If that's +4x, the answer is (x - 4)(x + 8) If that's -4x, the answer is (x + 4)(x - 8)

x2 + 4x - 32 = (x + 8)*(x - 4)

(x - 4) or (x + 8)

x2 - 4

x2 + 4x - 96 = (x - 8)(x + 12).

4x(x2 - 2)

x(x - 4)

x2 + 4x + 6 can not be factored. If you want, you can reduce it to an expression with a single x term by comleting the square: x2 + 4x + 6 = x2 + 4x + 4 + 2 = (x + 2)2 + 2

x2 + 4x - 60 factors into (x + 10)(x - 6). You can use the FOIL method to check your answers when you factor.
