Question

What is the integral of −8x^2−8x−4dx

Answer 1

integral of ax^n = a x^(n+1)
-------
n+1

Answer 2

\[\int\limits_{}^{}(a+b)dx=\int\limits_{}^{}(a)dx+\int\limits_{}^{}(b)dx\]
\[\int\limits_{}^{}x^{n-1}dx=\frac{x^n}{n}\]

Answer 3

oh - don't forget the arbitrary constant +C

Answer 4

i plugged that in and it did not work

Answer 5

lol you cannot plug the general form in as the solution.

Answer 6

You must use the general form to solve for your particular case.

Answer 7

i know i used the formula, but did not get the right answer. can you help me?

Answer 8

Sure. What did you get?

Answer 9

-8x+C

Answer 10

ax^n = a x^(n+1)
-------
n+1

Answer 11

The first term is −8x^2

Answer 12

so
a= -8
n = 2

Answer 13

plug in those to the formula

Answer 14

Then do the next term

Answer 15

i plugged them in, but its still now working
