F(x)=(5-2x/3x-1)

Solution for F(x)=(5-2x/3x-1) equation:

(F)=(5-2F/3F-1)

We move all terms to the left:

(F)-((5-2F/3F-1))=0


Domain of the equation: 3F-1))!=0

F∈R


We add all the numbers together, and all the variables

F-((-2F/3F+4))=0

We multiply all the terms by the denominator


F*3F-2F+4))-((=0

We add all the numbers together, and all the variables

-2F+F*3F=0

Wy multiply elements

3F^2-2F=0

a = 3; b = -2; c = 0;
Δ = b2-4ac
Δ = -22-4·3·0
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$F_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$F_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4}=2$
$F_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-2)-2}{2*3}=\frac{0}{6}
=0
$
$F_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2)+2}{2*3}=\frac{4}{6}
=2/3
