1-121x^2=0

Solution for 1-121x^2=0 equation:

1-121x^2=0

a = -121; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·(-121)·1
Δ = 484
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{484}=22$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-22}{2*-121}=\frac{-22}{-242}
=1/11
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+22}{2*-121}=\frac{22}{-242}
=-1/11
