(F)=2F^2+5F+10
We move all terms to the left:
(F)-(2F^2+5F+10)=0
We get rid of parentheses
-2F^2+F-5F-10=0
We add all the numbers together, and all the variables
-2F^2-4F-10=0
a = -2; b = -4; c = -10;
Δ = b2-4ac
Δ = -42-4·(-2)·(-10)
Δ = -64
Delta is less than zero, so there is no solution for the equation
