16x^2+47x-30=0
a = 16; b = 47; c = -30;
Δ = b2-4ac
Δ = 472-4·16·(-30)
Δ = 4129
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(47)-\sqrt{4129}}{2*16}=\frac{-47-\sqrt{4129}}{32} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(47)+\sqrt{4129}}{2*16}=\frac{-47+\sqrt{4129}}{32} $
