6x*6x-76*6x+1=0

Wy multiply elements

36x^2-456x+1=0

a = 36; b = -456; c = +1;
Δ = b2-4ac
Δ = -4562-4·36·1
Δ = 207792
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:

$\sqrt{\Delta}=\sqrt{207792}=\sqrt{144*1443}=\sqrt{144}*\sqrt{1443}=12\sqrt{1443}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-456)-12\sqrt{1443}}{2*36}=\frac{456-12\sqrt{1443}}{72}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-456)+12\sqrt{1443}}{2*36}=\frac{456+12\sqrt{1443}}{72}
