# Finding Indefinite Integrals In Exercises 7-18, find the indefinite integral Check your result by differentiating. See Examples 1 and 2. ∫ 2 x   d x

To determine

To calculate: The indefinite integral 2xdx and verify the result by differentiation.

Explanation

Given Information:

The provided indefinite integral is 2xdx.

Formula used:

The integration and differentiation formulae used are:

1. ddx[(f(x))]=f(x)

2. k dx=kx+ C

3. xn dx=xn+1n+1+ C

4. ddx[(f(x))]=f'(x)

5. ddx[kx]=k

6. ddx[xn]=nxn1

Here, C is the constant of integration.

Calculation:

Consider the indefinite integral 2xdx.

Now, use the formulae k dx=kx+C and xn dx=xn+1n+1+C to evaluate the integral as:

2xdx=2[x1+12]+C=x2+C

Thus, the indefinite integral is evaluated as x2+C
