-x^2-6x-8=2x^2
We move all terms to the left:
-x^2-6x-8-(2x^2)=0
determiningTheFunctionDomain -x^2-2x^2-6x-8=0
We add all the numbers together, and all the variables
-3x^2-6x-8=0
a = -3; b = -6; c = -8;
Δ = b2-4ac
Δ = -62-4·(-3)·(-8)
Δ = -60
Delta is less than zero, so there is no solution for the equation
