2y^2+17y+15=0
a = 2; b = 17; c = +15;
Δ = b2-4ac
Δ = 172-4·2·15
Δ = 169
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{169}=13$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(17)-13}{2*2}=\frac{-30}{4} =-7+1/2 $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(17)+13}{2*2}=\frac{-4}{4} =-1 $
