x^2-7x-160=0
a = 1; b = -7; c = -160;
Δ = b2-4ac
Δ = -72-4·1·(-160)
Δ = 689
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{-(-7)-\sqrt{689}}{2*1}=\frac{7-\sqrt{689}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+\sqrt{689}}{2*1}=\frac{7+\sqrt{689}}{2} $
