Question 16

Coordinate axes show a curve, a vertical boundary line, and a region labelled R between the curve and the x-axis.

The curve C C\,C with equation y=6−x(2x−3)(x+2)\displaystyle y = \frac{6 - x}{(2x - 3)(x + 2)}y=(2x−3)(x+2)6−x​. The region R R\,R is bounded by the curve CCC, the xxx-axis and the line with equation x=2x = 2x=2.

Show that the exact value of the area of R R\,R is aln⁡2+bln⁡3a \ln 2 + b \ln 3aln2+bln3, where a a\,a and b b\,b are rational constants to be found.
