(R)=R2-200R+10125
We move all terms to the left:
(R)-(R2-200R+10125)=0
We add all the numbers together, and all the variables
-(+R^2-200R+10125)+R=0
We get rid of parentheses
-R^2+200R+R-10125=0
We add all the numbers together, and all the variables
-1R^2+201R-10125=0
a = -1; b = 201; c = -10125;
Δ = b2-4ac
Δ = 2012-4·(-1)·(-10125)
Δ = -99
Delta is less than zero, so there is no solution for the equation
