((2x+1)(x-5))/(x+3)=0 Start with the given equation.


(2x+1)(x-5)=0(x+3) Divide both sides by x+3.


(2x+1)(x-5)=0 Multiply


2x^2-9x-5=0 FOIL


(x-5)(2x+1)=0 Factor the left side.


x-5=0 or 2x+1=0 Set each factor equal to zero.


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



So the solutions are x=5 or x=-1/2
