On a line, you go to the left 6 times from the origin on x-axis. When y=0, that is the x-intercept

Answer:

a = - 3, b = 5

Step-by-step explanation:

To rationalise the denominator multiply the numerator/ denominator by $\sqrt{2}$

= $\frac{\sqrt{2}(10-\sqrt{18}) }{(\sqrt{2})^2 }$

= $\frac{10\sqrt{2}-\sqrt{36} }{2}$

= $\frac{10\sqrt{2}-6 }{2}$

= 5 $\sqrt{2}$ - 3

= - 3 + 5 $\sqrt{2}$ ← in the form a + b $\sqrt{2}$

with a = - 3 and b = 5

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 $x$ .

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