Wy multiply elements

10x^2-1900x+3=0

a = 10; b = -1900; c = +3;
Δ = b2-4ac
Δ = -19002-4·10·3
Δ = 3609880
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{3609880}=\sqrt{4*902470}=\sqrt{4}*\sqrt{902470}=2\sqrt{902470}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1900)-2\sqrt{902470}}{2*10}=\frac{1900-2\sqrt{902470}}{20}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1900)+2\sqrt{902470}}{2*10}=\frac{1900+2\sqrt{902470}}{20}
