Homework Statement


Hi all.

I have to solve [itex]0=-x^4+x^2+\alpha[/itex], where alpha is a constant. I thought of factorizing it, but this won't work.You guys have any tip for solving this?

Thanks in advance.Niles.

If you substitute u=x^2, it turns into a quadratic equation.
 
Ahh, so simple. I hadn't thought of that.

Thanks.
