Question

Is x - 8 a factor of the function f(x) = -2x3 + 17x2 - 64? Explain.

Answer 1

Yes. When the function f(x) = -2x3 + 17x2 - 64 is divided by x - 8, the remainder is zero. Therefore, x - 8 is a factor of f(x) = -2x3 + 17x2 - 64.
No. When the function f(x) = -2x3 + 17x2 - 64 is divided by x - 8, the remainder is zero. Therefore, x - 8 is not a factor of f(x) = -2x3 + 17x2 - 64.

Answer 2

I know it's between the first option and 3rd option :)

Answer 3

well i divided it and the remainder is 2112 so the 3rd opinion is correct ;)

Answer 4

and please let me divide it again to be sure :)
