27x^2=127

Solution for 27x^2=127 equation:

27x^2=127

We move all terms to the left:

27x^2-(127)=0

a = 27; b = 0; c = -127;
Δ = b2-4ac
Δ = 02-4·27·(-127)
Δ = 13716
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:

$\sqrt{\Delta}=\sqrt{13716}=\sqrt{36*381}=\sqrt{36}*\sqrt{381}=6\sqrt{381}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{381}}{2*27}=\frac{0-6\sqrt{381}}{54}
=-\frac{6\sqrt{381}}{54}
=-\frac{\sqrt{381}}{9}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{381}}{2*27}=\frac{0+6\sqrt{381}}{54}
=\frac{6\sqrt{381}}{54}
=\frac{\sqrt{381}}{9}
