2x^2+8x+60=18-
We move all terms to the left:
2x^2+8x+60-(18-)=0
We add all the numbers together, and all the variables
2x^2+8x+60-0=0
We add all the numbers together, and all the variables
2x^2+8x+60=0
a = 2; b = 8; c = +60;
Δ = b2-4ac
Δ = 82-4·2·60
Δ = -416
Delta is less than zero, so there is no solution for the equation
