Solution for -1/11x^2+11=0 equation:

-1/11x^2+11=0


Domain of the equation: 11x^2!=0

x^2!=0/11

x^2!=√0

x!=0

x∈R


We multiply all the terms by the denominator


11*11x^2-1=0

Wy multiply elements

121x^2-1=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
