Complete the square on the bottom.

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...

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

What is your problem exactly ?

7. ## Missing line/calulation

What I cannot figure out is how we get

0.46y2 + 1.84y + 1.84 = 2.87

8. 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

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