-16.39y(y+1)+100

We multiply parentheses

-16y^2-16y+100

Back to the equation:

-(-16y^2-16y+100)



We get rid of parentheses

-20y^2+16y^2+16y+0.0819y-100+72.99=0

We add all the numbers together, and all the variables

-4y^2+16.0819y-27.01=0

a = -4; b = 16.0819; c = -27.01;
Δ = b2-4ac
Δ = 16.08192-4·(-4)·(-27.01)
Δ = -173.53249239
Delta is less than zero, so there is no solution for the equation
