    5x2 + 5x 4x2 + 2x= 20
    Write this in the standard form.
    Then x = [-b + or - sqrt( b^2 - 4ac)]/2a.
    Now solve.

    Collect x^2 and x terms together and bring the constant term to the left side and write down the equation which equals to zero.
    Identify coefficients of x^2 and x and hence a, b and c.
    Substitute them in the standard formula to find x
