(F)=4F^2-3F+1
We move all terms to the left:
(F)-(4F^2-3F+1)=0
We get rid of parentheses
-4F^2+F+3F-1=0
We add all the numbers together, and all the variables
-4F^2+4F-1=0
a = -4; b = 4; c = -1;
Δ = b2-4ac
Δ = 42-4·(-4)·(-1)
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$F=\frac{-b}{2a}=\frac{-4}{-8}=1/2$
