1/6*x=100

Solution for 1/6*x=100 equation:

1/6*x=100

We move all terms to the left:

1/6*x-(100)=0


Domain of the equation: 6*x!=0

x!=0/1

x!=0

x∈R


We multiply all the terms by the denominator


-100*6*x+1=0

Wy multiply elements

-600x*x+1=0

Wy multiply elements

-600x^2+1=0

a = -600; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·(-600)·1
Δ = 2400
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:

$\sqrt{\Delta}=\sqrt{2400}=\sqrt{400*6}=\sqrt{400}*\sqrt{6}=20\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-20\sqrt{6}}{2*-600}=\frac{0-20\sqrt{6}}{-1200}
=-\frac{20\sqrt{6}}{-1200}
=-\frac{\sqrt{6}}{-60}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+20\sqrt{6}}{2*-600}=\frac{0+20\sqrt{6}}{-1200}
=\frac{20\sqrt{6}}{-1200}
=\frac{\sqrt{6}}{-60}
