Answer:
Step-by-step explanation:
6x^5 - 4x^4 + 4x^3
The powers add so done term by term you get
2*3 x ^(3 + 2) = 6x^5
2x^2 *(-2 x^2) = - 4x^(2 + 2) = -4x^4
2x^2 * 2x = 4x^(2 + 1) = 4x^3
You put the 6 into the lower green box and 5 into the upper green box.
You use the same pattern for the other 2 terms.
