-2.3x^2+5x+9.8=0
a = -2.3; b = 5; c = +9.8;
Δ = b2-4ac
Δ = 52-4·(-2.3)·9.8
Δ = 115.16
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{-(5)-\sqrt{115.16}}{2*-2.3}=\frac{-5-\sqrt{115.16}}{-4.6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+\sqrt{115.16}}{2*-2.3}=\frac{-5+\sqrt{115.16}}{-4.6} $
