-x^2-11x-17=0
We add all the numbers together, and all the variables
-1x^2-11x-17=0
a = -1; b = -11; c = -17;
Δ = b2-4ac
Δ = -112-4·(-1)·(-17)
Δ = 53
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{-(-11)-\sqrt{53}}{2*-1}=\frac{11-\sqrt{53}}{-2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+\sqrt{53}}{2*-1}=\frac{11+\sqrt{53}}{-2} $
