198=22x^2

Solution for 198=22x^2 equation:

198=22x^2

We move all terms to the left:

198-(22x^2)=0

a = -22; b = 0; c = +198;
Δ = b2-4ac
Δ = 02-4·(-22)·198
Δ = 17424
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{17424}=132$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-132}{2*-22}=\frac{-132}{-44}
=+3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+132}{2*-22}=\frac{132}{-44}
=-3
