78.74+18.52y(0.006515-y)=100-10.53y(1+y)

Solution for 78.74+18.52y(0.006515-y)=100-10.53y(1+y) equation:

78.74+18.52y(0.006515-y)=100-10.53y(1+y)

We move all terms to the left:

78.74+18.52y(0.006515-y)-(100-10.53y(1+y))=0

We add all the numbers together, and all the variables

18.52y(-1y+0.006515)-(100-10.53y(y+1))+78.74=0

We multiply parentheses

-18y^2+0.11727y-(100-10.53y(y+1))+78.74=0


We calculate terms in parentheses: -(100-10.53y(y+1)), so:

100-10.53y(y+1)

-10.53y(y+1)+100

We multiply parentheses

-10y^2-10y+100

Back to the equation:

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


We get rid of parentheses

-18y^2+10y^2+10y+0.11727y-100+78.74=0

We add all the numbers together, and all the variables

-8y^2+10.11727y-21.26=0

a = -8; b = 10.11727; c = -21.26;
Δ = b2-4ac
Δ = 10.117272-4·(-8)·(-21.26)
Δ = -577.9608477471
Delta is less than zero, so there is no solution for the equation
