    Solving Quadratic Equations by the Quadratic Formula

    Hey guys, I am having trouble with this problem that consists on fractions.

    I know how to solve using quadratic formula but I don't know what step I should do for this one

    Solve each equation:

    (x-4) / (x^2 + 2) = 2

    Re: Solving Quadratic Equations by the Quadratic Formula

    I would multiply through by x^2+2 first...

    Multiply both sides by x^2 + 2 which gets me x-4 = 2x^2 + 4 and then move everything to either the right or left?

    It really doesn't matter, as long as one side is zero. I would move everything to the right, then combine like terms and arrange with the zero on the right side. Now you will have the equation in standard quadratic form.

    Sweet, I got the correct answer. It's quite funny how simple it was. Guess I can't see the simplest things sometimes haha. Thanks a lot.
