Question

Simplify:(2x+8)(7x^2-9x-5)

Answer 1

A 14x^3+74x^2+62x-40
B 14x^3+38x^2+62x-40
C 14x^3+38x^2+82x-40
D 14x^3+74x^2+82x-40

Answer 2

Starting with this\[(2x+8)(7x ^{2-}9x-5)\]
\[=(2x+8)(7x ^{2}+−9x+−5)\]\[=(2x)(7x ^{2})+(2x)(−9x)+(2x)(−5)+(8)(7x ^{2})+(8)(−9x)+(8)(−5)\]\[=14x ^{3}−18x ^{2}−10x+56x ^{2}−72x−40\]\[=14x ^{3}+38x ^{2}−82x−40\]
Final answer\[=14x ^{3}+38x ^{2}−82x−40\]
