Question

Approximate the real number solutions to the polynomial function f(x) = x^3 – 2x^2 – 16x + 32 .

Answer 1

Hint:
Let f(x) = 0 and factor by grouping to get
0 = x^2(x-2)-16(x-2)
0 = (x-2)(x^2 - 16)

Answer 2

I've got the answers... I think. I came to -4 , 4, and 2. Does that seem right?

Answer 3

You don't have to "approximate" You can get the actual number

Answer 4

Yup so

3 real
0 imaginary

Answer 5

Thank you.
