(R)=4R^2+16.000
We move all terms to the left:
(R)-(4R^2+16.000)=0
We get rid of parentheses
-4R^2+R-16.000=0
We add all the numbers together, and all the variables
-4R^2+R-16=0
a = -4; b = 1; c = -16;
Δ = b2-4ac
Δ = 12-4·(-4)·(-16)
Δ = -255
Delta is less than zero, so there is no solution for the equation
