-4.9x^2+29.4x+2.5=0
a = -4.9; b = 29.4; c = +2.5;
Δ = b2-4ac
Δ = 29.42-4·(-4.9)·2.5
Δ = 913.36
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{-(29.4)-\sqrt{913.36}}{2*-4.9}=\frac{-29.4-\sqrt{913.36}}{-9.8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(29.4)+\sqrt{913.36}}{2*-4.9}=\frac{-29.4+\sqrt{913.36}}{-9.8} $
