5x^2+x+20=2x^2
We move all terms to the left:
5x^2+x+20-(2x^2)=0
determiningTheFunctionDomain 5x^2-2x^2+x+20=0
We add all the numbers together, and all the variables
3x^2+x+20=0
a = 3; b = 1; c = +20;
Δ = b2-4ac
Δ = 12-4·3·20
Δ = -239
Delta is less than zero, so there is no solution for the equation
