To determine

To calculate: The indefinite integral x2+2x+5x1dx.

Explanation

Given Information:

The provided indefinite integral is x2+2x+5x1dx.

Formula used:

The general logarithmic rule of integrals:

1ududxdx=ln|u|+C

The general power rule of integration:

undu=un+1n+1+C

The constant rule of integration:

cdu=cu+C

Calculation:

Consider the indefinite integral:

x2+2x+5x1dx

Rewrite the integrand as:

x2+2x+5x1dx=x2+3xx3+8x1dx=x(x+3)1(x+3)+8x1dx=(x+3)(x1)+8x1
