$$x^{3} - 2x^{2} - 13x + 6$$

Work Step by Step

To evaluate this expression, we will use the FOIL method to distribute terms. First, we will multiply the first term, $x$, with each of the terms within the second pair of parentheses. Then we will multiply the second term with each of the terms in the second pair of parentheses: $$x^{3} - 5x^{2} + 2x + 3x^{2} -15x + 6$$ Combine like terms: $$x^{3} - 2x^{2} - 13x + 6$$
