9.8x^2-140x+300=0
a = 9.8; b = -140; c = +300;
Δ = b2-4ac
Δ = -1402-4·9.8·300
Δ = 7840
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{7840}=\sqrt{784*10}=\sqrt{784}*\sqrt{10}=28\sqrt{10}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-140)-28\sqrt{10}}{2*9.8}=\frac{140-28\sqrt{10}}{19.6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-140)+28\sqrt{10}}{2*9.8}=\frac{140+28\sqrt{10}}{19.6} $
