0=y^2-10y+26
We move all terms to the left:
0-(y^2-10y+26)=0
We add all the numbers together, and all the variables
-(y^2-10y+26)=0
We get rid of parentheses
-y^2+10y-26=0
We add all the numbers together, and all the variables
-1y^2+10y-26=0
a = -1; b = 10; c = -26;
Δ = b2-4ac
Δ = 102-4·(-1)·(-26)
Δ = -4
Delta is less than zero, so there is no solution for the equation
