We multiply parentheses
11x^2-297=0
a = 11; b = 0; c = -297;
Δ = b2-4ac
Δ = 02-4·11·(-297)
Δ = 13068
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:
$\sqrt{\Delta}=\sqrt{13068}=\sqrt{4356*3}=\sqrt{4356}*\sqrt{3}=66\sqrt{3}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-66\sqrt{3}}{2*11}=\frac{0-66\sqrt{3}}{22} =-\frac{66\sqrt{3}}{22} =-3\sqrt{3} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+66\sqrt{3}}{2*11}=\frac{0+66\sqrt{3}}{22} =\frac{66\sqrt{3}}{22} =3\sqrt{3} $
