Solution for 3x2+5x+1=0 equation: 



3x^2+5x+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:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

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


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