13x^2-66x+5=0
a = 13; b = -66; c = +5;
Δ = b2-4ac
Δ = -662-4·13·5
Δ = 4096
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4096}=64$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-66)-64}{2*13}=\frac{2}{26} =1/13 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-66)+64}{2*13}=\frac{130}{26} =5 $
