3w^2+5w+1=0

a = 3; b = 5; c = +1;
Δ = b2-4ac
Δ = 52-4·3·1
Δ = 13
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-\sqrt{13}}{2*3}=\frac{-5-\sqrt{13}}{6}
$


$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{13}}{2*3}=\frac{-5+\sqrt{13}}{6}
$
