Answer:

−3x3−16x2−14x+8

Step-by-step explanation:

first times the first x in parentheses by everything in the second

(x)(-3x^2) and (x)(-4x) and (x)(2)

-3x^3-4x^2+2x

Then times the 4 by the other variables in the parentheses

(4)(-3x^2) and (4)(-4x) and (4)(2)

-12x^2-16x+8

now the whole equation:  

-3x^3-4x^2+2x -12x^2-16x+8

now you must simplify or add like terms

-3x^3-16x^2-14x+8 is your answer, which is the first one.
