F(X)=2x+6/X+4

Solution for F(X)=2x+6/X+4 equation:

(F)=2F+6/F+4

We move all terms to the left:

(F)-(2F+6/F+4)=0


Domain of the equation: F+4)!=0

F∈R


We get rid of parentheses

F-2F-6/F-4=0

We multiply all the terms by the denominator


F*F-2F*F-4*F-6=0

We add all the numbers together, and all the variables

-4F+F*F-2F*F-6=0

Wy multiply elements

F^2-2F^2-4F-6=0

We add all the numbers together, and all the variables

-1F^2-4F-6=0

a = -1; b = -4; c = -6;
Δ = b2-4ac
Δ = -42-4·(-1)·(-6)
Δ = -8
Delta is less than zero, so there is no solution for the equation
