(F)=2F^2+20F+51
We move all terms to the left:
(F)-(2F^2+20F+51)=0
We get rid of parentheses
-2F^2+F-20F-51=0
We add all the numbers together, and all the variables
-2F^2-19F-51=0
a = -2; b = -19; c = -51;
Δ = b2-4ac
Δ = -192-4·(-2)·(-51)
Δ = -47
Delta is less than zero, so there is no solution for the equation
