We get rid of parentheses
100n^2-30n-10n+3=0
We add all the numbers together, and all the variables
100n^2-40n+3=0
a = 100; b = -40; c = +3;
Δ = b2-4ac
Δ = -402-4·100·3
Δ = 400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{400}=20$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-40)-20}{2*100}=\frac{20}{200} =1/10 $
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-40)+20}{2*100}=\frac{60}{200} =3/10 $
