Use integration tables to find the indefinite integral.

Let's rewrite the integrand as,

  --------------------(1)

Now let' evaluate each of the above two integrals separately,

Let's apply integral substitution:

Now from the integer tables:

Substitute back 

                    -----------------------------(2)

Now let's evaluate the second integral,

Take the constant out,

Complete the square of the term in the denominator.

Now use the following from the integration tables:

Now from the integration table:

Substitute back 

    -------------------------(3)

Plug back the results of the integrals 2 and 3 in 1

Add a constant C to the solution,
