(F)=3F^2+4F+8
We move all terms to the left:
(F)-(3F^2+4F+8)=0
We get rid of parentheses
-3F^2+F-4F-8=0
We add all the numbers together, and all the variables
-3F^2-3F-8=0
a = -3; b = -3; c = -8;
Δ = b2-4ac
Δ = -32-4·(-3)·(-8)
Δ = -87
Delta is less than zero, so there is no solution for the equation
