69.44+20y(0.005616-y)=100-12.82y(1+y)

Solution for 69.44+20y(0.005616-y)=100-12.82y(1+y) equation:

69.44+20y(0.005616-y)=100-12.82y(1+y)

We move all terms to the left:

69.44+20y(0.005616-y)-(100-12.82y(1+y))=0

We add all the numbers together, and all the variables

20y(-1y+0.005616)-(100-12.82y(y+1))+69.44=0

We multiply parentheses

-20y^2+0.11232y-(100-12.82y(y+1))+69.44=0


We calculate terms in parentheses: -(100-12.82y(y+1)), so:

100-12.82y(y+1)

-12.82y(y+1)+100

We multiply parentheses

-12y^2-12y+100

Back to the equation:

-(-12y^2-12y+100)


We get rid of parentheses

-20y^2+12y^2+12y+0.11232y-100+69.44=0

We add all the numbers together, and all the variables

-8y^2+12.11232y-30.56=0

a = -8; b = 12.11232; c = -30.56;
Δ = b2-4ac
Δ = 12.112322-4·(-8)·(-30.56)
Δ = -831.2117042176
Delta is less than zero, so there is no solution for the equation
