10.7+9.8x-4.9x^2=0
a = -4.9; b = 9.8; c = +10.7;
Δ = b2-4ac
Δ = 9.82-4·(-4.9)·10.7
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{-(9.8)-\sqrt{305.76}}{2*-4.9}=\frac{-9.8-\sqrt{305.76}}{-9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9.8)+\sqrt{305.76}}{2*-4.9}=\frac{-9.8+\sqrt{305.76}}{-9.8} $
