65.79+24.39y(0.003178-y)=100-19.61y(1+y)
We move all terms to the left:
65.79+24.39y(0.003178-y)-(100-19.61y(1+y))=0
We add all the numbers together, and all the variables
24.39y(-1y+0.003178)-(100-19.61y(y+1))+65.79=0
We multiply parentheses
-24y^2+0.076272y-(100-19.61y(y+1))+65.79=0
We calculate terms in parentheses: -(100-19.61y(y+1)), so:We get rid of parentheses
100-19.61y(y+1)
determiningTheFunctionDomain -19.61y(y+1)+100
We multiply parentheses
-19y^2-19y+100
Back to the equation:
-(-19y^2-19y+100)
-24y^2+19y^2+19y+0.076272y-100+65.79=0
We add all the numbers together, and all the variables
-5y^2+19.076272y-34.21=0
a = -5; b = 19.076272; c = -34.21;
Δ = b2-4ac
Δ = 19.0762722-4·(-5)·(-34.21)
Δ = -320.29584658202
Delta is less than zero, so there is no solution for the equation
