0=12x^2+8x+12
We move all terms to the left:
0-(12x^2+8x+12)=0
We add all the numbers together, and all the variables
-(12x^2+8x+12)=0
We get rid of parentheses
-12x^2-8x-12=0
a = -12; b = -8; c = -12;
Δ = b2-4ac
Δ = -82-4·(-12)·(-12)
Δ = -512
Delta is less than zero, so there is no solution for the equation
