Firstly thanks for your reply.

What I cannot figure out is how we get

0.46y2 + 1.84y + 1.84 = 2.87

Are you trying to solve this? Just get everything on one side and use the Quadratic formula...

When I multiply I get different figures than 0.46y2 + 1.84y + 1.84 = 2.87.

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

You just have to multiply 0.080 par the denominator

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