27x2=27

Solution for 27x2=27 equation:

27x^2=27

We move all terms to the left:

27x^2-(27)=0

a = 27; b = 0; c = -27;
Δ = b2-4ac
Δ = 02-4·27·(-27)
Δ = 2916
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2916}=54$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-54}{2*27}=\frac{-54}{54}
=-1
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+54}{2*27}=\frac{54}{54}
=1
