^2+Y^2=13
We move all terms to the left:
^2+Y^2-(13)=0
determiningTheFunctionDomain Y^2-13+^2=0
We add all the numbers together, and all the variables
Y^2=0
a = 1; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·1·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$Y=\frac{-b}{2a}=\frac{0}{2}=0$
