I don't speak Romanian, but the closest translation for this suggests you're trying to compute

Integrate by parts:

where
u = ln(x)² ⇒ du = 2 ln(x)/x dx
dv = x³ dx ⇒ v = 1/4 x⁴

Integrate by parts again:

where
u' = ln(x) ⇒ du' = dx/x
dv' = x³ dx ⇒ v' = 1/4 x⁴

So, we have

Answer:

Step-by-step explanation:
Given the function
, to write the form of its partial fraction on decomposition, we will separate the two functions separated by an addition sign. The numerator of each function will be constants A and b and the denominator will be the individual factors of each function at the denominator. The partial fraction of the rational function is as shown below.

<em>Since we are not to solve for the constants, hence the partial fraction is </em>
