0=12x^2-180+500
We move all terms to the left:
0-(12x^2-180+500)=0
We add all the numbers together, and all the variables
-(12x^2-180+500)=0
We get rid of parentheses
-12x^2+180-500=0
We add all the numbers together, and all the variables
-12x^2-320=0
a = -12; b = 0; c = -320;
Δ = b2-4ac
Δ = 02-4·(-12)·(-320)
Δ = -15360
Delta is less than zero, so there is no solution for the equation
