Question 549

It is given that

f(x)=x−52x+3+2x+42x2+7x+6\displaystyle f(x) = \frac{x - 5}{2x + 3} + \frac{2x + 4}{2x^2 + 7x + 6}f(x)=2x+3x−5​+2x2+7x+62x+4​

a.

Express f(x)f(x)f(x) as a single fraction in its simplest form.

[3]
b.

Hence find f′(x)f'(x)f′(x), giving your answer in its simplest form.
