3-13x=3-8x%2Bx%5E2 Start with the given equation.


0=3-8x%2Bx%5E2-3%2B13x Get all terms to the right side.


0=x%5E2%2B5x Combine like terms.


x%5E2%2B5x=0 Rearrange the equation.


x%28x%2B5%29=0 Factor.


x=0 or x%2B5=0 Set each factor equal to zero.


x=0 or x=-5 Solve for "x"


So the solutions are x=0 or x=-5
