 Question 570645: Solve the equation by factoring. (2x/x+3)+(5/x)-4=(18/x^2+3x) -------------------------------- I have gotten this far with the problem.... LCM = X(x+3) thus I have 2x^2+5x+15-4x^2-12=18--->-2x^2+5x+3=18--->-2x^2+5x-15=0 I think my problem is the (-2x^2) which I got from 2x^2-4x^2 and the (-4x^2) is from multiplying the LCM (x(x+3))to -4.
