Wy multiply elements
-344n^2+90n+1=0
a = -344; b = 90; c = +1;
Δ = b2-4ac
Δ = 902-4·(-344)·1
Δ = 9476
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{9476}=\sqrt{4*2369}=\sqrt{4}*\sqrt{2369}=2\sqrt{2369}$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(90)-2\sqrt{2369}}{2*-344}=\frac{-90-2\sqrt{2369}}{-688} $
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(90)+2\sqrt{2369}}{2*-344}=\frac{-90+2\sqrt{2369}}{-688} $
