Hey, so i was revising for a math exam in a thew weeks and found this question,
integrate 1/6x^2 i keep getting -6x^-1 but the answer is -1/6x^-1 .
Can anyone explain this to me?
there are 10 types of people in this world,
those who understand binary and those who don't.

You obviously mean 1/(6x^2), which is NOT (1/6)x^2
1/(6x^2)
= 1/6 * (x^-2)
Now the integral of that:
1/6 * (-1) x^(-2 + 1) + c
=-(1/6) * (x^-1) + c
=-1/(6*x) + c
