Sagot :
(2a - 1) (a + 3) + (4a - 5) (a + 3) = (a+3)(2a-1+4a-5) = (a+3)(6a-6)
Réponse:
(a+3)(6a-6)
Explications étape par étape:
(2a - 1) (a + 3) + (4a - 5) (a + 3)
(a + 3) (2a - 1 + 4a - 5)
(a + 3) (6a - 6)
(2a - 1) (a + 3) + (4a - 5) (a + 3) = (a+3)(2a-1+4a-5) = (a+3)(6a-6)
Réponse:
(a+3)(6a-6)
Explications étape par étape:
(2a - 1) (a + 3) + (4a - 5) (a + 3)
(a + 3) (2a - 1 + 4a - 5)
(a + 3) (6a - 6)
