The volume of the box is represented by (X2 + 8x + 15)(x + 4). Find the polynomial that represents the area of the bottom of the box. x +5 EXAMPLE Writing Equivalent Forms of a Rational Expression Write four equivalent forms of the rational expression. 3x + 2 If we apply the negative sign to the numerator, we obtain these equivalent forms. (3x + 2) - 3x - 2 and, by the distributive property, If we apply the negative sign to the denominator, we obtain two more forms. 3x + 2 3x + 2 or, distributing once again, - (x - 6) -x + 6
