0=0.93x^2+2.2x+130
We move all terms to the left:
0-(0.93x^2+2.2x+130)=0
We add all the numbers together, and all the variables
-(0.93x^2+2.2x+130)=0
We get rid of parentheses
-0.93x^2-2.2x-130=0
a = -0.93; b = -2.2; c = -130;
Δ = b2-4ac
Δ = -2.22-4·(-0.93)·(-130)
Δ = -478.76
Delta is less than zero, so there is no solution for the equation
