0=-5x^2-12+12x
We move all terms to the left:
0-(-5x^2-12+12x)=0
We add all the numbers together, and all the variables
-(-5x^2-12+12x)=0
We get rid of parentheses
5x^2-12x+12=0
a = 5; b = -12; c = +12;
Δ = b2-4ac
Δ = -122-4·5·12
Δ = -96
Delta is less than zero, so there is no solution for the equation
