How do you integrate y = 4x^3 - 5/x^2?

First we should look at the formula for integrating xn. The integral is (xn+1 / n+1) + C.

Let's break down our equation into two parts. 

  1. The integral of 4x3 = 4(x3+1 / 3+1) = 4(x/ 4) = x4

  2. The integral of -5/x2 = -5(x-2+1 / -2+1) = -5(x-1 / -1) = 5(x-1) = 5/x

So the integral of y = x + 5/x + C
