(F)=0.5F^2-3F+9.5
We move all terms to the left:
(F)-(0.5F^2-3F+9.5)=0
We get rid of parentheses
-0.5F^2+F+3F-9.5=0
We add all the numbers together, and all the variables
-0.5F^2+4F-9.5=0
a = -0.5; b = 4; c = -9.5;
Δ = b2-4ac
Δ = 42-4·(-0.5)·(-9.5)
Δ = -3
Delta is less than zero, so there is no solution for the equation
