(d - 9) · (2d² + 11d - 4)
First distribute the "d" into (2d² + 11d - 4), then distribute -9 into (2d² + 11d - 4)
2d³ + 11d² - 4d - 18d² - 99d + 36
2d³ - 7d² - 103d + 36
Answer:
2d^3-7d^2-103d+36
Step-by-step explanation:
(d-9)(2d^2+11d-4)
2d^3+11d^2-4d-18d^2-99d+36
2d^3+11d^2-18d^2-4d-99d+36
2d^3-7d^2-103d+36
