Trouble with factorising a polynomial

I'm supposed to show that: $$y=\frac{5(x-1)(x+2)}{(x-2)(x+3)} = P + \frac{Q}{(x-2)} + \frac{R}{(x+3)}$$ and the required answers are: $$ P=5, Q=4, R=-4 $$ I tried to solve this with partial ...

How do I factor this kind of equations?

I was doing some integration by partial fractions exercises and I found this equation:$$\int_{0}^{1}\frac{x^{3}+1}{x^{4}+4x+3},$$ and I don't know how to factor that in order to compute the partial ...
