14z^2+27z-2=0
a = 14; b = 27; c = -2;
Δ = b2-4ac
Δ = 272-4·14·(-2)
Δ = 841
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{841}=29$$z_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(27)-29}{2*14}=\frac{-56}{28} =-2 $$z_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(27)+29}{2*14}=\frac{2}{28} =1/14 $
