Salut à tous,J'espère que vous pourrais m'aider ça serais gentil,il faut remplir le tableau en détailant,Merci beaucoup (merci d'avance)

Bonjour

♤ 1/

● a = 5
● b = -3
● c = -4
● A = a² = 5² = 25
● B = b² = (-3)² = 9
● D = ab = 5×(-3) = - 15
● E = bc = -3×(-4) = 12
.
♤ 2/

● a = 7
● b = -2
● c = - 8
● A = a² = 7² = 49
● B = b² = (-2)² = 4
● D = ab = 7× (-2) = - 14
● E = bc = -2×(-8) = 16

♤ 3/

● a = 4
● b = 3
● c = 0
● A = a² = 4² = 16
● B = b² = 3² = 9
● D = ab = 3 × 4 = 12
● E = bc = -2×0 = 0

Voilà ^^
