1313400=-2.09x^2+77.84x+744
We move all terms to the left:
1313400-(-2.09x^2+77.84x+744)=0
We get rid of parentheses
2.09x^2-77.84x-744+1313400=0
We add all the numbers together, and all the variables
2.09x^2-77.84x+1312656=0
a = 2.09; b = -77.84; c = +1312656;
Δ = b2-4ac
Δ = -77.842-4·2.09·1312656
Δ = -10967745.0944
Delta is less than zero, so there is no solution for the equation
