Question

Approximate the real number solution(s) to the polynomial function f(x) = x^3 – 2x^2 – 5x + 6 .
Answer:
A)x = 3, x = –1, x = 2
B)x = –3, x = 1, x = –2
C)x = 3, x = 1, x = –2
D)x = –3, x = –1, x = 2

Answer 1

Well, you could plug in the answers and see which ones work or you could use synthetic division to try and factor it.
