x∈R


We add all the numbers together, and all the variables

(+1/4)(x+111)-55=0

We multiply parentheses ..

(+x^2+1/4*111)-55=0

We multiply all the terms by the denominator


(+x^2+1-55*4*111)=0

We get rid of parentheses

x^2+1-55*4*111=0

We add all the numbers together, and all the variables

x^2-24419=0

a = 1; b = 0; c = -24419;
Δ = b2-4ac
Δ = 02-4·1·(-24419)
Δ = 97676
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:

$\sqrt{\Delta}=\sqrt{97676}=\sqrt{4*24419}=\sqrt{4}*\sqrt{24419}=2\sqrt{24419}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{24419}}{2*1}=\frac{0-2\sqrt{24419}}{2}
=-\frac{2\sqrt{24419}}{2}
=-\sqrt{24419}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{24419}}{2*1}=\frac{0+2\sqrt{24419}}{2}
=\frac{2\sqrt{24419}}{2}
=\sqrt{24419}
