9x^2-10000=0

Solution for 9x^2-10000=0 equation:

9x^2-10000=0

a = 9; b = 0; c = -10000;
Δ = b2-4ac
Δ = 02-4·9·(-10000)
Δ = 360000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{360000}=600$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-600}{2*9}=\frac{-600}{18}
=-33+1/3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+600}{2*9}=\frac{600}{18}
=33+1/3
