0=x^2+0x+3
We move all terms to the left:
0-(x^2+0x+3)=0
We add all the numbers together, and all the variables
-(x^2+0x+3)=0
We get rid of parentheses
-x^2-0x-3=0
We add all the numbers together, and all the variables
-1x^2-1x-3=0
a = -1; b = -1; c = -3;
Δ = b2-4ac
Δ = -12-4·(-1)·(-3)
Δ = -11
Delta is less than zero, so there is no solution for the equation
