Answer: 6x^3 - 5x^2 - 39x + 35
Step-by-step explanation: Multiply each term in the first set of parentheses by each term in the second set of parentheses. Multiply the coefficients and add the exponents. 2x(3x2) + 2x(5x) + 2x(-7) -5(3x2) - 5(5x) - 5(-7) = 6x3 + 10x2 - 14x - 15x2 - 25x + 35. Combine like terms. The correct answer is 6x^3 - 5x^2 - 39x + 35 .
