81.3+15.63y(0.007164-y)=100-10.99y(1+y)

Solution for 81.3+15.63y(0.007164-y)=100-10.99y(1+y) equation:

81.3+15.63y(0.007164-y)=100-10.99y(1+y)

We move all terms to the left:

81.3+15.63y(0.007164-y)-(100-10.99y(1+y))=0

We add all the numbers together, and all the variables

15.63y(-1y+0.007164)-(100-10.99y(y+1))+81.3=0

We multiply parentheses

-15y^2+0.10746y-(100-10.99y(y+1))+81.3=0


We calculate terms in parentheses: -(100-10.99y(y+1)), so:

100-10.99y(y+1)

-10.99y(y+1)+100

We multiply parentheses

-10y^2-10y+100

Back to the equation:

-(-10y^2-10y+100)


We get rid of parentheses

-15y^2+10y^2+10y+0.10746y-100+81.3=0

We add all the numbers together, and all the variables

-5y^2+10.10746y-18.7=0

a = -5; b = 10.10746; c = -18.7;
Δ = b2-4ac
Δ = 10.107462-4·(-5)·(-18.7)
Δ = -271.8392523484
Delta is less than zero, so there is no solution for the equation
