  1. Sep 24, 2009 #1
    1. The problem statement, all variables and given/known data

    x^2 - 1/2x - 3/16 = 0

    3. The attempt at a solution
    Actually, I don't know where to start since I have fractions.

    Your mention of "Square Root Method" is not clear. Since you have two fractions in the left-hand expression, use what you have known since having "learned" about fractions; which is, find the lowest common denominator, and multiply both sides of the equation by it. In your example, the L.C.D. is 16*x.

    If you perform this multiplication, you will effectively clear away the fractions. If done correctly, you should obtain a CUBIC equation.

    Now, by curiosity, please explain what is this Square Root Method about which you want some help?
