(x)=2x^2+3x+6
We move all terms to the left:
(x)-(2x^2+3x+6)=0
We get rid of parentheses
-2x^2+x-3x-6=0
We add all the numbers together, and all the variables
-2x^2-2x-6=0
a = -2; b = -2; c = -6;
Δ = b2-4ac
Δ = -22-4·(-2)·(-6)
Δ = -44
Delta is less than zero, so there is no solution for the equation
