=Y2+13
We move all terms to the left:
-(Y2+13)=0
We add all the numbers together, and all the variables
-(+Y^2+13)=0
We get rid of parentheses
-Y^2-13=0
We add all the numbers together, and all the variables
-1Y^2-13=0
a = -1; b = 0; c = -13;
Δ = b2-4ac
Δ = 02-4·(-1)·(-13)
Δ = -52
Delta is less than zero, so there is no solution for the equation
