    You can't factor this but since you set it equal to zero, I believe you meant to say solve it

    Oh, okay - I wasn't sure if it could be factored. So, yes - I guess it would be "solve it." Ha, ha - thanks for the correction. :)

    sometimes you can factor a quadratic to solve it, in this case, you can not factor it and therefore it is best to use the quadratic formula remember the decimal solutions are approximations the one I wrote above is an exact solution
