12y^2+3y-1=0

a = 12; b = 3; c = -1;
Δ = b2-4ac
Δ = 32-4·12·(-1)
Δ = 57
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{-(3)-\sqrt{57}}{2*12}=\frac{-3-\sqrt{57}}{24}
$


$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{57}}{2*12}=\frac{-3+\sqrt{57}}{24}
$
