Jsp Comment Faire Jai Honte Mais Je Demande De Laide Svp class=

Sagot :

A = 8x - 12

A = 4×2x - 4×3

A = 4 ×(2x - 3)

A = 4 (2x - 3)

B = 7x² - 21x

B = 7x × x - 7x × 3

B = 7x × (x - 3)

B = 7x(x - 3)

C = (x - 5) (x + 2) - (x - 5)(5x + 1)

C = (x - 5) × [ (x + 2) - (5x + 1)]

C = (x - 5) × [x + 2 - 5x - 1  ]

C = (x - 5) (- 4x + 1)

D = 2x + 3 + 5x(2x + 3)

D = (2x + 3) × 1 + (2x + 3) × 5x

D = (2x + 3)  × (1 + 5x)

D = (2x + 3)(1 + 5x)
