608=x*x

Solution for 608=x*x equation:

608=x*x

We move all terms to the left:

608-(x*x)=0

We add all the numbers together, and all the variables

-(+x*x)+608=0

We get rid of parentheses

-x*x+608=0

Wy multiply elements

-1x^2+608=0

a = -1; b = 0; c = +608;
Δ = b2-4ac
Δ = 02-4·(-1)·608
Δ = 2432
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:

$\sqrt{\Delta}=\sqrt{2432}=\sqrt{64*38}=\sqrt{64}*\sqrt{38}=8\sqrt{38}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{38}}{2*-1}=\frac{0-8\sqrt{38}}{-2}
=-\frac{8\sqrt{38}}{-2}
=-\frac{4\sqrt{38}}{-1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{38}}{2*-1}=\frac{0+8\sqrt{38}}{-2}
=\frac{8\sqrt{38}}{-2}
=\frac{4\sqrt{38}}{-1}
