Hi!

Could someone please solve this for me and explain how to do?

(3/5)x^2 - 2x -5 = 0

I know how to solve this kind of equations but I don't know how to do when I have (3/5)X^2. Because I'm told to multiply the x-term so that it'll be 1. But if I do that I get 10x. And that'll cause problems later on when I'm supposed to get the square root of ten
