Question

I cannot seem to get past this step in this equation, here is how far I am
x^4-3x^2=-2x^2
x^4-3x^2+2x^2=0
x(x^3-3x+2x)=0


Can anyone help me?

Answer 1

From that second to third step, you can actually factor out x^2

Answer 2

Oh wow...Thanks!

Answer 3

Would the step after look like this then?

x^2(x^2-3+2)
x(x-2)(x-1)
x=0
x=2
x=1
