Wy multiply elements

210x^2-189000=0

a = 210; b = 0; c = -189000;
Δ = b2-4ac
Δ = 02-4·210·(-189000)
Δ = 158760000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{158760000}=12600$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12600}{2*210}=\frac{-12600}{420}
=-30
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12600}{2*210}=\frac{12600}{420}
=30
