: solve the equasion by cross multiplying. check each solution.
41) -1/x-3 = x-4/x^2-27
i attempted: -x^2+27 = x^2-7x+12 = -2x^2+27 = -7x+12 = -2x^2 = -7x+39
= 2x^2-7x+39=0 ?????????? This question is from textbook

You were almost there. Just a little misstep with a sign. You were correct up to the point where you said:



But then you added a -27 on the left and +27 on the right, where you should have added -27 to both sides resulting in:





Which factors rather tidily to:



Can you take it from there?
