o n° =x

consecutivo ímpar= x + 2

então o produto deles é:

x(x +2) = 143

x² + 2x=143                                            os n° são:

x² +2x -143=0                                        1°)  x= 11

Δ=4 +572                                                2°) x +2= 11+2=13

Δ=576    √Δ=24                                             ou

x=( -2 + 24)/2= 22/2= 11                         1°) x= -13

x= (-2 - 24)/2= - 26/2= -13                        2°) x + 2= -13 +2= -11
