30a^2+17a-2=0
a = 30; b = 17; c = -2;
Δ = b2-4ac
Δ = 172-4·30·(-2)
Δ = 529
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{529}=23$$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(17)-23}{2*30}=\frac{-40}{60} =-2/3 $$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(17)+23}{2*30}=\frac{6}{60} =1/10 $
