Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R


We get rid of parentheses

1/2x-2x+37-4=0

We multiply all the terms by the denominator


-2x*2x+37*2x-4*2x+1=0

Wy multiply elements

-4x^2+74x-8x+1=0

We add all the numbers together, and all the variables

-4x^2+66x+1=0

a = -4; b = 66; c = +1;
Δ = b2-4ac
Δ = 662-4·(-4)·1
Δ = 4372
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:

$\sqrt{\Delta}=\sqrt{4372}=\sqrt{4*1093}=\sqrt{4}*\sqrt{1093}=2\sqrt{1093}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(66)-2\sqrt{1093}}{2*-4}=\frac{-66-2\sqrt{1093}}{-8}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(66)+2\sqrt{1093}}{2*-4}=\frac{-66+2\sqrt{1093}}{-8}
