%28%282x%2B1%29%28x-5%29%29%2F%28x%2B3%29=0 Start with the given equation.


%282x%2B1%29%28x-5%29=0%28x%2B3%29 Divide both sides by x%2B3.


%282x%2B1%29%28x-5%29=0 Multiply


2x%5E2-9x-5=0 FOIL


%28x-5%29%282x%2B1%29=0 Factor the left side.


x-5=0 or 2x%2B1=0 Set each factor equal to zero.


x=5 or x=-1%2F2 Solve for x in each case.



So the solutions are x=5 or x=-1%2F2
