x2-11x-14=0
We add all the numbers together, and all the variables
x^2-11x-14=0
a = 1; b = -11; c = -14;
Δ = b2-4ac
Δ = -112-4·1·(-14)
Δ = 177
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{177}}{2*1}=\frac{11-\sqrt{177}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+\sqrt{177}}{2*1}=\frac{11+\sqrt{177}}{2} $
