Question

is x-8 a factor of the function f(x)=-2x^3+17x^2-64?Explain

Answer 1

Answer:

Yes.

Step-by-step explanation:

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.

Answer 2

Answer:

  yes

Step-by-step explanation:

x-8 will be a factor if f(8) = 0.

f(8) = -2(8^3) +17(8^2) -64 = 64(-16 +17 -1) = 0

Yes, x-8 is a factor.
