bonjour

H = ( x + 5 ) ( x + 3 - 3 )

  =  x ( x + 5 )

I = ( x - 4 ) ( 2 x + 3 + 3 x - 5 )

 = ( x - 4 ) ( 5 x - 2 )

J = ( x - 8 ) ( 3 x - 1 - 2 x - 4 )

  = ( x - 8 ) ( x - 5 )

K = ( x - 5 ) ( x + 2 - 3 x - 1 )

  = ( x - 5 ) ( - 2 x + 1 )

L = ( 3 x - 1 ) ( x - 2 - 2 x - 5 )

  = ( 3 x - 1 ) ( - x - 7 )

M = ( 2 x + 3 ) ( x - 7 )

Bonjour;

H = (x+5) ( x+3 -3)

= (x+5) ( x)

I= (x-4) ( 2x+3 +3x-5)

= (x-4) (5x -2)

J= (x-8) ( 3x-1 -2x -4)

= (x-8) ( x -5)

K =  (x-5) ( x+2 -3x -1)

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

L= (3x-1) ( x-2 -2x -5)

=  (3x-1) ( -x -7)

M = (2x+3) ( x -7)
