    Quadratic equation - Wikipedia, the free encyclopedia

    For any quadratic equation, in the form ax^2+bx+c = 0, it has root(s):

    (-b +/- (b^2 - 4ac)^0.5) / 4a

    Therefore we take your equation, express it so it's equal to zero:

    4x^2 - 7x + 2 = 0

    Then it's plug-and-play with the quadratic formula:

    (7 +/- (49 - 4(4)(2))^0.5) / 4(4)

    = (7 +/- (33)^0.5) / 16
