2p^2-14p-16=0
a = 2; b = -14; c = -16;
Δ = b2-4ac
Δ = -142-4·2·(-16)
Δ = 324
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{324}=18$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-14)-18}{2*2}=\frac{-4}{4} =-1 $
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-14)+18}{2*2}=\frac{32}{4} =8 $
