is the same as . All real numbers will satisfy this except x = 3/2, when it is zero. Thus the solution set is (, 3/2)U(3/2, ).
4x^2 - 3x - 6 = 0
Check the discriminant:. The value of the discriminant is positive but is not a perfect square, so the quadratic expression cannot be factored into linear factors with rational coefficients.
