-11=2.6495x-4.905x^2
We move all terms to the left:
-11-(2.6495x-4.905x^2)=0
We get rid of parentheses
4.905x^2-2.6495x-11=0
a = 4.905; b = -2.6495; c = -11;
Δ = b2-4ac
Δ = -2.64952-4·4.905·(-11)
Δ = 222.83985025
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{-(-2.6495)-\sqrt{222.83985025}}{2*4.905}=\frac{2.6495-\sqrt{222.83985025}}{9.81} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2.6495)+\sqrt{222.83985025}}{2*4.905}=\frac{2.6495+\sqrt{222.83985025}}{9.81} $
