Answer
20% for the first one
Answer:
Step-by-step explanation:
8x² - 5x + 3x(4 - 2x) =8x² - 5x + 3x*4 - 3x*2x
= 8x² - 5x + 12x - 6x²
Now add the like terms
= 8x² - 6x² - 5x + 12x
= 2x² + 7x


By the power rule,

(this seems to be the step you're not getting?)

The next step is to pull out a common factor of
from the antiderivative:

so that the final result is
