List the possible rational solutions of the equation.

A rectangular prism has sides of lengths x, x, and x – 1, and a volume of 24 cubic inches. Write a polynomial equation to model the situation. List the possible rational solutions of the equation, and then find the dimensions of the prism.

24 = (x)(x)(x - 1)

24 = x3 - x2


Can you solve for x and answer?

Use the Rational Root Theorem to identify the possible rational roots (x values), then test each one to see if it's a solution. Since this is a cubic equation, you will have either 1 or 3 roots (answers).
