Given that

5x+3(x−1)(3x+1)2≡Ax−1+B3x+1+C(3x+1)2\frac{5x+3}{(x-1)(3x+1)^2} \equiv \frac{A}{x-1} + \frac{B}{3x+1} + \frac{C}{(3x+1)^2}(x−1)(3x+1)25x+3​≡x−1A​+3x+1B​+(3x+1)2C​

a.

find the values of the constants AAA, BBB and CCC.

[4]
b.

Hence find the exact value of

∫235x+3(x−1)(3x+1)2 dx\int_{2}^{3} \frac{5x+3}{(x-1)(3x+1)^2} \,\mathrm{d}x∫23​(x−1)(3x+1)25x+3​dx

giving your answer in the form pln⁡q+rp \ln q + rplnq+r where ppp, qqq and rrr are rational numbers.
