Ok so I'm in grade 12 taking math. Were working on polynomial functions and factoring. It's got to be the hardest stuff yet but looking forward at the curriculum that comment will look like a joke. Anyways here's the question that I'm stuck on.

-4x^4 + 60x^3 = 200x^2

This is my first post so I apologize if I'm not posting in the correct sub forum. I searched the forum and this seemed to be the most appropriate area. Any help would be great. Thanks.
