Answer:

x³ + 2x² - 22x +12

Step-by-step explanation:

( x + 6 ) ( x² - 4x + 2 ) = x³ - 4x² + 2x + 6x² - 24x + 12

= x³ + 2x² - 22x +12

Answer: x³+2x²-22x+12

Step-by-step explanation:

the product of functions: (hg)(x)

Use FOIL to solve this (First Outer Inner Later)

(x+6)(x²-4x+2)

=x³-4x²+2x+6x²-24x+12

=x³-4x²+6x²+2x-24x+12

=x³+2x²-22x+12

Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.

7(x-2)=28
7X-14=28
7x=42
X=6
