15w^2+22w+8=0
a = 15; b = 22; c = +8;
Δ = b2-4ac
Δ = 222-4·15·8
Δ = 4
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{4}=2$$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(22)-2}{2*15}=\frac{-24}{30} =-4/5 $$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(22)+2}{2*15}=\frac{-20}{30} =-2/3 $
