So, you need us to sub in numbers for you?

Evaluating at x = 3 gives:

(1/3)(3)^4 - 2(3)^3

(1/3)(81) - 2(27)

27 - 2(27)

-27

Evaluating at x = -3:

(1/2)(-3)^4 - 2(-3)^3

(1/2)(81) + 2(27)

27 + 2(27)

81

Done!

x^2 + 6x + 8 (x+4)(x+2) xy + 5y - x - 5 y(x + 5) -a million(x+5) (y-a million)(x+5) Are you lacking an X interior the third question? If the question is 4x^3 -x^2 - 12x + 3, right here is the respond... x^2(4x - a million) -3(4x - a million) (x^2 - 3)(4x - a million)
