X=100/10x

Solution for X=100/10x equation:

X=100/10X

We move all terms to the left:

X-(100/10X)=0


Domain of the equation: 10X)!=0

X!=0/1

X!=0

X∈R


We add all the numbers together, and all the variables

X-(+100/10X)=0

We get rid of parentheses

X-100/10X=0

We multiply all the terms by the denominator


X*10X-100=0

Wy multiply elements

10X^2-100=0

a = 10; b = 0; c = -100;
Δ = b2-4ac
Δ = 02-4·10·(-100)
Δ = 4000
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:

$\sqrt{\Delta}=\sqrt{4000}=\sqrt{400*10}=\sqrt{400}*\sqrt{10}=20\sqrt{10}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-20\sqrt{10}}{2*10}=\frac{0-20\sqrt{10}}{20}
=-\frac{20\sqrt{10}}{20}
=-\sqrt{10}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+20\sqrt{10}}{2*10}=\frac{0+20\sqrt{10}}{20}
=\frac{20\sqrt{10}}{20}
=\sqrt{10}
