    If so, start by factoring the numerator. Then cancel any common term in the numerator and denominator. If you end up with no denominator, then use the original denominator. Set it equal to zero and solve for x. That value of x will be the restriction.

    So 3x - 5, with the restriction x ≠ -five over 3? @mathstudent55
