(C)=C^2-25C+200
We move all terms to the left:
(C)-(C^2-25C+200)=0
We get rid of parentheses
-C^2+C+25C-200=0
We add all the numbers together, and all the variables
-1C^2+26C-200=0
a = -1; b = 26; c = -200;
Δ = b2-4ac
Δ = 262-4·(-1)·(-200)
Δ = -124
Delta is less than zero, so there is no solution for the equation
