-4.9x^2+14x+5.6=0
a = -4.9; b = 14; c = +5.6;
Δ = b2-4ac
Δ = 142-4·(-4.9)·5.6
Δ = 305.76
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{-(14)-\sqrt{305.76}}{2*-4.9}=\frac{-14-\sqrt{305.76}}{-9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+\sqrt{305.76}}{2*-4.9}=\frac{-14+\sqrt{305.76}}{-9.8} $
