Question

Quizplus · Accepted Answer

The rational root theorem suggests that any rational root, expressed as a fraction p/q, must have p as a factor of the constant term (-18) and q as a factor of the leading coefficient (147). Testing these possibilities, $x = \frac{2}{3}$ satisfies the equation.
