Evaluate integral 3x(X-2) from 0 to 2 and comment on your answer.

Answer 1

?? This is just a simple application of the power rule
∫3x(x-2) dx = 3∫x^2 - 2x dx
Surely that isn't too hard?

Answer 2

Perhaps the "comment on your answer" refers to the fact that
the answer turned out negative, and Raj did not realize that the region
lies below the x-axis.
Always make a sketch to understand what the question deals with.
