10k^2-1210=0

Solution for 10k^2-1210=0 equation:

10k^2-1210=0

a = 10; b = 0; c = -1210;
Δ = b2-4ac
Δ = 02-4·10·(-1210)
Δ = 48400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{48400}=220$
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-220}{2*10}=\frac{-220}{20}
=-11
$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+220}{2*10}=\frac{220}{20}
=11
