For this, we adapted a didactic sequence with activities that aims to cause a rediscovery of resolutive formula of 2nd degree equation through the method known as cut and paste. Finally, we presented the activity module containing the didactic sequence used during the study, as suggestion for use in the classroom, by the math teacher / O presente estudo tem como objetivo verificar se o uso de atividades mediadas pela Hist?ria da Matem?tica pode contribuir para a melhoria da compreens?o da resolu??o da equa??o do 2? grau para professores e licenciandos que reproduzem m?todos de resolu??o de tais equa??es, de maneira acr?tica, sem o dom?nio das justificativas de suas a??es. Para isso, adaptamos uma sequ?ncia did?tica com atividades que tem como prop?sito fazer com que haja uma redescoberta da f?rmula resolutiva da equa??o do 2? grau atrav?s do m?todo denominado corte e cole. Por fim, apresentamos o m?dulo de atividades contendo a sequ?ncia did?tica utilizada durante o estudo, como sugest?o para uso em sala de aula, pelo professor de matem?tica
