how do you simplify a problem like
x=-30x/2x^2?
Answered by drwls
Cancel the common factor 2x that appears in both numerator and denominator.

x = -30x/2x^2
= -(15*2x)/(2x*x)]
= -15/x

wait so it isn't the square root of 15?

Sorry, I did not notice that is was an equation. I was just rewriting the right hand side.

x would be the imaginary number
+ or - i sqrt15
