Answer: Last option.

Step-by-step explanation:

For this exercise you need to find the Discriminant.

The formula used to find the Discriminant, is the following:

$D=b^2-4ac$

In this case, given the Quadratic equation:

$6x^2-2x+7=0$

You can identify that:

$a=6\\b=-2\\c=7$

Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.

You get that this is:

$D=(-2)^2-4(6)(7)\\\\D=-164$

By definition, if:

$D$

Then the Quadraitc equation has 2 nonreal solutions.

Substitute $u=x^2+4$ and $du=2x\,dx$ . Then the integral transforms to

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \int \frac{du}{u^3}$

Apply the power rule.

$\displaystyle \int \frac{du}{u^3} = -\dfrac1{2u^2} + C$

Now put the result back in terms of $x$ .

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \left(-\dfrac1{2u^2} + C\right) = -\dfrac1{4u^2} + C = \boxed{-\dfrac1{4(x^2+4)^2} + C}$
