There are lots of methods possible for solving a quadratic equation they should all work for any given problem, but one might be easier than another. If you have two terms, look to factor and set each factor equal to zero using the zero product property. If there is no "b" term, add the constant to both sides, isolate the x^2, and then square root both sides (remember to use + and  roots.) If factoring wont work, you could always use the quadratic formula. If you have a trinomial where "a" is one and "b" is even, consider completing the square. Lastly, if you have access to a graphing technology, try graphing the function and finding the xintercepts.
