Homework Help: Algebra

Posted by Katie on Wednesday, October 7, 2009 at 5:22pm.

4x^4-18x^2=0. I have to find out what x equals by factoring. What I did was

Factor 2x^2(2x^2+-9)=0 then 2x^2(2x+3)(x+-3), resulting in -1.5 and three. But these answers are wrong according to my book. Can you show me step by step how to do this correctly? It would be a huge help!
