Pourriez-vous m’aidez à factoriser ces expressions svp ​

bonsoir

E = ( x + 3 )² - 9

E = ( x + 3 - 3 ) ( x + 3 + 3)

E =  x ( x + 6 )

G = ( 5x - 2 )² - 16

G  = ( 5 x - 2 - 4 ) ( 5 x - 2 + 4 )

G = ( 5 x - 6 ) ( 5 x + 2 )

I = ( 2 x + 6 )² - 64

I = ( 2 x + 6 - 8 ) ( 2 x + 6 + 8 )

I = ( 2 x - 2 ) ( 2 x + 14 )

F =  100 - ( 2 x + 1 )²

F = ( 10 + 2 x + 1 ) ( 10 - 2 x - 1 )

F = ( 2 x + 11 ) ( - 2 x + 9 )

H = 81 - ( 5 x + 6 ) ²

H = ( 9 + 5 x + 6 ) ( 9 - 5 x - 6 )

H = ( 5 x + 15 ) ( - 5 x + 3 )
