Pouvez vous m'aider svp 49y2 + 14y = 7y ×__+ 7y ×__=7y(__+__) 9n2 - 6n = 3n × __ - __ × __ = 3n(__-__) 8t2 + 6t + 2 = 2 ×__+ 2 ×__+ 2 ×__= 2 × (__)

Réponse :

49y2 + 14y = 7y ×7y+ 7y ×2=7y(7y+2)

9n2 - 6n = 3n × 3n - 3n × 2 = 3n(3n-2)

8t2 + 6t + 2 = 2 ×4t²+ 2 ×3t+ 2 ×1= 2 × (4t²+3t+1)

Bonjour,

49y² + 14y = 7y × 7y + 7y × 2 =7y (7y + 2)

9n² - 6n = 3n × 3n - 3n × - 2= 3n(3n - 2)

8t² + 6t + 2 = 2 × 4t² + 2 × 3t + 2 × 1 = 2 × (4t² + 3t + 1)
