Δ = b2-4ac
Δ = -1142-4·16·14
Δ = 12100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{12100}=110$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-114)-110}{2*16}=\frac{4}{32}
=1/8
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-114)+110}{2*16}=\frac{224}{32}
=7
