FACTORISER LES EXPRESSIONS SUIVANTES :

G = (7x + 3)(9x - 5) + (7x + 3)(4x + 2)

H = (4x - 3)² - (4x - 3)(2x + 1)

MERCI D'AVANCE :)

Sagot :

(7x+3)(9x-5)+(7x+3)(4x+2)
(7x+3)(9x-5+4x+2)
(7x+3)(13x-3)

(4x-3)²-(4x-3)(2x+1)
(4x-3)(4x-3)-(2x+1)
(4x-3)(4x-3-2x-1)
(4x-3)(2x-4)

G = (7x+3)(9x-5)+(7x+3)(4x+2)
   = (7x+3) [(9x-5) + (4x+3)]
   = (7x+3) (9x-5 + 4x +3)
   = (7x+3) (13x -2)
H = (4x-3)² - (4x-3)(2x+1)
   = (4x-3) [(4x-3) - (2x+1)]
   = (4x-3) (4x-3 - 2x-1)
   = (4x-3) (2x -4)
voilà ^^
