Answer:

cubic expression.

x3 - 2x2 - 4x + 8

Step-by-step explanation:

(x2 − 4) (x − 2)

first we will multiply both parenthesis

(x2 * x) + (x2 * -2) + (-4 * x) + (-4 * -2)

then you simplify the parenthesis

(x3) + (-2x2) + (-4x) + (8)

then we eliminate the parenthesis

x3 - 2x2 - 4x + 8

and finally we have an cubic expression

X3-2x2-4x+8. That is what the answer would be because if you do the foiling method (First, Outer, Inner, Last) or wither the box method, both methods should produce the same answer.
