We get rid of parentheses

x*x+125.44

Wy multiply elements

x^2+125.44

Back to the equation:

-(x^2+125.44)


We get rid of parentheses

-x^2-125.44+432.64=0

We add all the numbers together, and all the variables

-1x^2+307.2=0

a = -1; b = 0; c = +307.2;
Δ = b2-4ac
Δ = 02-4·(-1)·307.2
Δ = 1228.8
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{1228.8}}{2*-1}=\frac{0-\sqrt{1228.8}}{-2}
=-\frac{\sqrt{}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1228.8}}{2*-1}=\frac{0+\sqrt{1228.8}}{-2}
=\frac{\sqrt{}}{-2}
