18w^2+2w-16=0
a = 18; b = 2; c = -16;
Δ = b2-4ac
Δ = 22-4·18·(-16)
Δ = 1156
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1156}=34$$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-34}{2*18}=\frac{-36}{36} =-1 $$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+34}{2*18}=\frac{32}{36} =8/9 $
