Integrating quadratics?
posted by Now What Do I Do? on .
find the antiderivative of f(x) = x^3(x2)^2
I factored this out and got
x^54x^4+4x^2
I'm supposed to integrate this. I don't know how. Someone help me please?
BTW, multiple choice options are:
A
B
C
D

Sorry, let me fix that. Multiple Choice options are:
A: 1/6 x^6  4/5 X^5 + x^4 + C
B: 1/6 x^6  4/5 X^5 + 1/4 x^4 + C
C: x^6  X^5 + x^4 + C
D: x^5  4x^4 + 4x^3 + C

You had asked for the antiderivative, and I had replied with "integrate"
That is the more "mathematical" terminology.
To "integrate" something is the same as finding the "antiderivative"
e.g.
the derivative of 6x^3 + 5x  2 is 18x^2 + 5
and the integral or the antiderivative of 18x^2 + 5 is 6x^3 + 5x
btw, I had a typo in my expanded form, should have been
x^5  4x^4 + 4x^3 , I am surprised you didn't check that
so the antiderivative or the integral of
x^5  4x^2 + 4x^3 is
(1/6)x^6  (4/5)x^5 + x^4 + C , where C is a constant
clearly choice a)
(differentiate choice a) and see what you get, to verify the answer)
