4.9x^2+12x-30.4=0
a = 4.9; b = 12; c = -30.4;
Δ = b2-4ac
Δ = 122-4·4.9·(-30.4)
Δ = 739.84
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{-(12)-\sqrt{739.84}}{2*4.9}=\frac{-12-\sqrt{739.84}}{9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(12)+\sqrt{739.84}}{2*4.9}=\frac{-12+\sqrt{739.84}}{9.8} $
