# In Problems 17-24, use integration by parts to evaluate the integral. Note that evaluation may require integration by parts more than once. ∫ 0 1 4 x 2 e x   d x

To determine

To calculate: The value of the integral 014x2exdx.

Explanation

Given Information:

The provided integral is 014x2exdx.

Formula used:

The formula for integration by parts is given by:

udv=uvvdu,

Calculation:

Consider the provided integral:

014x2exdx

Now, split the integrand into two parts setting one part equal to u and another part equal to dv.

So, the values will be:

u=4x2

And,

dv=exdx

Then,

du=8xdx

And,

v=exdx=ex+C

Then, use the formula for integration by parts:

udv=uvvdu

To obtain,

014x2exdx=[4x2ex]01801xexdx=4(1e10)801xexdx …… (1)

Now, again split the second integrand into two parts setting one part equal to u and another part equal to dv
