# Thread: Factoring/Finding What X is

1. ## Factoring/Finding What X is

Can someone help me with this.

432x -48x^2 + 4x^3 = 600

Can you either factor it or find the possibilities of X?

Hi bherrell2,

$432x-48x^2+4x^3=600$

Let's line everything up and simplify the equation.

$4x^3-48x^2+432x-600=0$

$x^3-12x^2+108x-150=0$

This thing has no rational roots. It has one real irrational root around 1.6497 and two imaginary roots.
