# Applying the General Power Rule In Exercises 9–34, find the indefinite integral. Check your result by differentiating. See Examples 1, 2, 3, and 5. ∫ 4 x + 6 ( x 2 + 3 x + 7 ) 3   d x

To determine

To calculate: The indefinite integral of 4x+6(x2+3x+7)3dx and check the result by differentiating.

Explanation

Given Information:

The indefinite integral is 4x+6(x2+3x+7)3dx.

Formula used:

General Power Rule:

If u is a differentiable function of x, then

undudxdx=undu=un+1n+1+c,n1

The Power Rule:

ddxxn=nxn1

Where n is a real number.

Calculation:

Consider indefinite integral,

4x+6(x2+3x+7)3dx

The above indefinite integral 4x+6(x2+3x+7)3dx be written as (x2+3x+7)3(4x+6)dx.

Let u=x2+3x+7,

So,

du=(2x+3) dx

Now use the general power rule to get,

(x2+3x+7)3(4x+6)dx=2(u)3du

Now the integral will be:

2(u)3du=2u3+13+1
