Solution for 4.9x^2-4.82x-1.2=0 equation:

4.9x^2-4.82x-1.2=0
a = 4.9; b = -4.82; c = -1.2;Δ = b2-4acΔ = -4.822-4·4.9·(-1.2)Δ = 46.7524The delta value is higher than zero, so the equation has two solutionsWe 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{-(-4.82)-\sqrt{46.7524}}{2*4.9}=\frac{4.82-\sqrt{46.7524}}{9.8}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4.82)+\sqrt{46.7524}}{2*4.9}=\frac{4.82+\sqrt{46.7524}}{9.8}$
