Δ = b2-4ac
Δ = 6122-4·912·0
Δ = 374544
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{374544}=612$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(612)-612}{2*912}=\frac{-1224}{1824}
=-51/76
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(612)+612}{2*912}=\frac{0}{1824}
=0
