So we are having a holiday right now and I decide to go over the math which I'm bad at "partial fraction"

The question is my exercise book is

so I work around with the algebra a bit and got the equation to become

the problem is that I wasn't sure how to integrate this since I cannot factorise the denominator into somethign like (x^2+A)(x+B)

so how does one set up for partial fractions

Best Regards
