1. The problem statement, all variables and given/known data

$$\int$$10/(x-1)(x^2-9)

2. Relevant equations

3. The attempt at a solution

I believe I should integrate by partial fractions here, but I'm not entirely sure on the notation. I've seen examples in my textbook that sometimes use B as opposed to Bx. Is this when that notation corresponds to a x^2?

Can this be done without having a factor of x in the numerator? If so would I just stick a +0x in the numerator before I seperate?

x2-9 can be factored as (x-3)(x+3)

$$\frac{1}{x-A)(ax^2+bx+c)}$$
$$\frac{F}{x-A}+\frac{Gx+H}{ax^2+bx+c}$$
