Solve the quadratic equation.

3x^2-15x+18=0

I know that the formula to quadratic equation is x=-b+and-(square root)b^2-4ac divided by 2a.

I know that a=3, b=-15 and c=18, then subsitute in and get two answers, my problem is that I keep getting an answer that does not work after I subsitute in the original equation. What do I do?
