X^2-6x+8=192

Solution for X^2-6x+8=192 equation:

X^2-6X+8=192

We move all terms to the left:

X^2-6X+8-(192)=0

We add all the numbers together, and all the variables

X^2-6X-184=0

a = 1; b = -6; c = -184;
Δ = b2-4ac
Δ = -62-4·1·(-184)
Δ = 772
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:

$\sqrt{\Delta}=\sqrt{772}=\sqrt{4*193}=\sqrt{4}*\sqrt{193}=2\sqrt{193}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-6)-2\sqrt{193}}{2*1}=\frac{6-2\sqrt{193}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-6)+2\sqrt{193}}{2*1}=\frac{6+2\sqrt{193}}{2}
