x=-2+34/x

Solution for x=-2+34/x equation:

x=-2+34/x

We move all terms to the left:

x-(-2+34/x)=0


Domain of the equation: x)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

x-(34/x-2)=0

We get rid of parentheses

x-34/x+2=0

We multiply all the terms by the denominator


x*x+2*x-34=0

We add all the numbers together, and all the variables

2x+x*x-34=0

Wy multiply elements

x^2+2x-34=0

a = 1; b = 2; c = -34;
Δ = b2-4ac
Δ = 22-4·1·(-34)
Δ = 140
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{140}=\sqrt{4*35}=\sqrt{4}*\sqrt{35}=2\sqrt{35}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{35}}{2*1}=\frac{-2-2\sqrt{35}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{35}}{2*1}=\frac{-2+2\sqrt{35}}{2}
