Answer:
(x² + 4x + 2)(2x² + 3x - 4) equals 2x⁴ + 11x³ + 12x² - 10x - 8
Step-by-step explanation:
<em>(x² + 4x + 2)(2x² + 3x - 4)</em>
Multiply each term in the first parentheses into the expression in the second parentheses.
<em>2x⁴ + 3x³ - 4x² + 8x³ + 12x² - 16x + 4x² + 6x - 8</em>
Combine like terms.
<em>2x⁴ + 11x³ + 12x² - 10x - 8</em>
So, your answer would be letter choice B.
