(C)=5C^2-1500C+126500
We move all terms to the left:
(C)-(5C^2-1500C+126500)=0
We get rid of parentheses
-5C^2+C+1500C-126500=0
We add all the numbers together, and all the variables
-5C^2+1501C-126500=0
a = -5; b = 1501; c = -126500;
Δ = b2-4ac
Δ = 15012-4·(-5)·(-126500)
Δ = -276999
Delta is less than zero, so there is no solution for the equation
