-2y+3(y-1)y=-1
We move all terms to the left:
-2y+3(y-1)y-(-1)=0
We add all the numbers together, and all the variables
-2y+3(y-1)y+1=0
We multiply parentheses
3y^2-2y-3y+1=0
We add all the numbers together, and all the variables
3y^2-5y+1=0
a = 3; b = -5; c = +1;
Δ = b2-4ac
Δ = -52-4·3·1
Δ = 13
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-\sqrt{13}}{2*3}=\frac{5-\sqrt{13}}{6} $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{13}}{2*3}=\frac{5+\sqrt{13}}{6} $
