Bonsoir

M = ( 15 x +7 ) ( 3 - x + 12 x + 5 )

M = ( 15 x + 7 ) ( 11 x + 8 )

S =  (13 x + 5 ) ( - 5 x + 2 - 8 x + 15 )

 = ( 13 x + 5 ) ( - 13 x + 17 )

Bonsoir,

Factoriser :

M = (15x+7)(3-x)+(15x+7)(12x+5)

M = (15x+7)(3-x+12x+5)

M = (15x+7)(8-x+12x)

M = (15x+7)(8+11x)

S = (13x+5)(-5x+2)-(13x+5)(8x-15)

S = (13x+5)(-5x+2-(8x-15))

S = (13x+5)(-5x+2-8x+15)

S = (13x+5)(-13x+2+15)

S = (13x+5)(-13x+17)

Bonne soirée.
