(F)=3F+1/F-2
We move all terms to the left:
(F)-(3F+1/F-2)=0
Domain of the equation: F-2)!=0We get rid of parentheses
F∈R
F-3F-1/F+2=0
We multiply all the terms by the denominator
F*F-3F*F+2*F-1=0
We add all the numbers together, and all the variables
2F+F*F-3F*F-1=0
Wy multiply elements
F^2-3F^2+2F-1=0
We add all the numbers together, and all the variables
-2F^2+2F-1=0
a = -2; b = 2; c = -1;
Δ = b2-4ac
Δ = 22-4·(-2)·(-1)
Δ = -4
Delta is less than zero, so there is no solution for the equation
