x^2-11^.5=0

Solution for x^2-11^.5=0 equation:

x^2-11^.5=0

We add all the numbers together, and all the variables

x^2-3.3166247903554=0

a = 1; b = 0; c = -3.3166247903554;
Δ = b2-4ac
Δ = 02-4·1·(-3.3166247903554)
Δ = 13.266499161422
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{13.266499161422}}{2*1}=\frac{0-\sqrt{13.266499161422}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{13.266499161422}}{2*1}=\frac{0+\sqrt{13.266499161422}}{2}
=\frac{\sqrt{}}{2}
