0=0.5y^2+0.25
We move all terms to the left:
0-(0.5y^2+0.25)=0
We add all the numbers together, and all the variables
-(0.5y^2+0.25)=0
We get rid of parentheses
-0.5y^2-0.25=0
a = -0.5; b = 0; c = -0.25;
Δ = b2-4ac
Δ = 02-4·(-0.5)·(-0.25)
Δ = -0.5
Delta is less than zero, so there is no solution for the equation
