Firstly thanks for your reply.

What I cannot figure out is how we get

**0.46y****2****+ 1.84y + 1.84 = 2.87**

When I multiply I get different figures than

**0.46y****2****+ 1.84y + 1.84 = 2.87.**

Starting from

$\displaystyle 0.080 = 0.051 \,\frac{56.25}{5.76 y^2 + 23.04 y + 23.04}$

You just have to multiply 0.080 par the denominator

$\displaystyle 0.080 \,(5.76 y^2 + 23.04 y + 23.04) = 0.051 \,\, 56.25 = 2.87$
