Answer:
Step-by-step explanation:
(3x² + 4x + 4)(2x - 4)
The easiest method is probably to use long multiplication.
3x² + 4x + 4
<u>2x - 4 </u>
6x³ + 8x² + 8x
<u> - 12x² - 16x - 16</u>
6x³ - 4x² - 8x -16
Since y is 5.2 you can substitute it in your equations 5.2 = -5x - 40 then you do things like normal add 40 in both sides and divide -5 in both sides you get 9.04
