x2-5x-135=0
We add all the numbers together, and all the variables
x^2-5x-135=0
a = 1; b = -5; c = -135;
Δ = b2-4ac
Δ = -52-4·1·(-135)
Δ = 565
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{-(-5)-\sqrt{565}}{2*1}=\frac{5-\sqrt{565}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+\sqrt{565}}{2*1}=\frac{5+\sqrt{565}}{2} $
