x²+6x+5= 0

a= 1       b=   6      c= 5

Δ= b²-4ac                     x= -b+√Δ/2a                    x'=-b-√Δ/2a

Δ=6²-4(1)(5)                 x=-6+√16/2(1)                 x'=-6-√16/2(1)

Δ= 36-20                      x=(-6 +4)/2                      x'=(-6-4)/2

Δ=16                            x=-1                                x'=-5
