Exercício de progressão aritmética
Prove que, se (a,b,c) é uma P.A., então (a²(b+c), b²(a+c), c²(a+b)) também é. Nesse exercício eu comecei usando a propriedade distributiva e depois tirando em evidencia, não sei como chegar a forma b-a = c-b que é a prova, tentei encontrar a resposta no google mais não achei o exercício resolvido
