3x-16-(1/2x)=0


Domain of the equation: 2x)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

3x-(+1/2x)-16=0

We get rid of parentheses

3x-1/2x-16=0

We multiply all the terms by the denominator


3x*2x-16*2x-1=0

Wy multiply elements

6x^2-32x-1=0

a = 6; b = -32; c = -1;
Δ = b2-4ac
Δ = -322-4·6·(-1)
Δ = 1048
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:

$\sqrt{\Delta}=\sqrt{1048}=\sqrt{4*262}=\sqrt{4}*\sqrt{262}=2\sqrt{262}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-32)-2\sqrt{262}}{2*6}=\frac{32-2\sqrt{262}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-32)+2\sqrt{262}}{2*6}=\frac{32+2\sqrt{262}}{12}
