3y^2+7y+1=0

a = 3; b = 7; c = +1;
Δ = b2-4ac
Δ = 72-4·3·1
Δ = 37
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-\sqrt{37}}{2*3}=\frac{-7-\sqrt{37}}{6}
$


$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{37}}{2*3}=\frac{-7+\sqrt{37}}{6}
$
