Question

How do you solve the equation: 0=x^3 - x^2 -4x +4?

Answer 1

First of all, the x^3 - x^2 makes x^1 which is just x or 1x. Subtract 4x and you have -3x. Add 4 to make 1x or just x. So x = 0.

Answer 2

Greetings,

x^3 - x^2 - 4x + 4 = 0

x^2(x - 1) - 4(x - 1) = 0

(x^2 - 4)(x - 1) = 0

(x - 2)(x + 2)(x - 1) = 0

x = 2 or x = -2 or x = 1
