Sagot :

A=16x+4=4(4x+1)

B=9-72x=9(1-8x)

C=12-8x=4(3-2x)

D=-6x-18=-6(x+3)

E=9x+6=3(3x+2)

F=42-14x=2(21-7x)=14(3-x)

A=4 x 4x + 4 x 1

A=4( 4x +1)

 

B=9  x 1 - 9 x 9x

B=9(1+9x)

 

C=4 x 3 - 4 x 2x

C=4(3 - 2x)

 

D=-6 x 1x - 6 x 3

D=6(1x - 3)

 

E=3 x 3x + 3 x 3

E=3 (3x + 3)

 

F= 3 x 14 - 14 x 1x

F=14 (3 - 1x)
