x!=0

x∈R


We multiply all the terms by the denominator


630*315x^2-2=0

Wy multiply elements

198450x^2-2=0

a = 198450; b = 0; c = -2;
Δ = b2-4ac
Δ = 02-4·198450·(-2)
Δ = 1587600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1587600}=1260$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-1260}{2*198450}=\frac{-1260}{396900}
=-1/315
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+1260}{2*198450}=\frac{1260}{396900}
=1/315
