Question

Approximate the real number solution(s) to the polynomial function f(x) = x3 + 2x2 - 5x - 6

Answer 1

x = -3, x = -1, x = 2
x = 3, x = 1, x = -2
x = 3, x = -1, x = 2
x = -3, x = 1, x = -2

Answer 2

Rewrite it as \( f(x)= (x+1)(x-2)(x+3) \). That is possible, if I didn't do any careless mistake. Can you see the solutions now?
