    2y2 + 3y + 1/2y2 - 5y -3 = 0
    2.5y2 - 2y - 3 = 0
    Multiply by 2 in order to get rid of incomplete numbers.
    5y2 - 4y - 6 = 0
    Finding the two solutions of the quadratic equation by the quadratic formula


    x=\frac{-b \pm \sqrt {b^2-4ac}}{2a},
    y1 = [4 + √(16 - 4 x 5 x -6)] / 2 x 5= 4 + 11.6619037896906 = 15.6619037896906
    y2 = [4 - √(16 - 4 x 5 x -6)] / 2 x 5= 4 - 11.6619037896906 = -7.6619037896906
