x-1/x=1-x

Solution for x-1/x=1-x equation:

x-1/x=1-x

We move all terms to the left:

x-1/x-(1-x)=0


Domain of the equation: x!=0

x∈R


We add all the numbers together, and all the variables

x-1/x-(-1x+1)=0

We get rid of parentheses

x-1/x+1x-1=0

We multiply all the terms by the denominator


x*x+1x*x-1*x-1=0

We add all the numbers together, and all the variables

-1x+x*x+1x*x-1=0

Wy multiply elements

x^2+x^2-1x-1=0

We add all the numbers together, and all the variables

2x^2-1x-1=0

a = 2; b = -1; c = -1;
Δ = b2-4ac
Δ = -12-4·2·(-1)
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-3}{2*2}=\frac{-2}{4}
=-1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+3}{2*2}=\frac{4}{4}
=1
