Question

how do you solve -3u=u^2

Answer 1

Try and divide both side by u.

Answer 2

So then u= -3?

Answer 3

Yeah, but you are missing something, sorry, I jumped to conclusion.

Do it a different way. add both sides by 3u and we have \(0 = u^2+3u\)

Factor u out: \(0 = u(u+3)\)

So \(\boxed{u=0,-3}\)

Answer 4

does that make sense?

Answer 5

oh that makes more sense thank you ^_^
