-14x^2-55x+9=0
a = -14; b = -55; c = +9;
Δ = b2-4ac
Δ = -552-4·(-14)·9
Δ = 3529
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{-(-55)-\sqrt{3529}}{2*-14}=\frac{55-\sqrt{3529}}{-28} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-55)+\sqrt{3529}}{2*-14}=\frac{55+\sqrt{3529}}{-28} $
