The integral of a function times a constant ($y^2$) is equal to the constant times the integral of the function

The integral of the exponential function is given by the following formula $\displaystyle \int a^xdx=\frac{a^x}{\ln(a)}$, where $a > 0$ and $a \neq 1$

As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
