7x^2+23x+168=6x^2+3x+7
We move all terms to the left:
7x^2+23x+168-(6x^2+3x+7)=0
We get rid of parentheses
7x^2-6x^2+23x-3x-7+168=0
We add all the numbers together, and all the variables
x^2+20x+161=0
a = 1; b = 20; c = +161;
Δ = b2-4ac
Δ = 202-4·1·161
Δ = -244
Delta is less than zero, so there is no solution for the equation
