Bonjour pouvez vous m’aidez sa fait 2 jours que je suis bloquer

Compléter les factorisations suivantes :

A = 4z2 + 12z + 9

A=(...... )2+2x......x......+......2

A = ( ...... + ...... )2


B = 16r2 – 40r + 25

B = ...... 2 – 2 x ...... x ...... + ...... 2

B = ( ...... - ...... )2


C = 9t2 – 64

C = ...... 2 - ...... 2

C = ( ...... + ...... )( ...... - ...... )


D = 49 – 70y + 25y2

D = ..................................................................

D = ..................................................................


E = d2 – 16

E = ..................................................................

E = ..................................................................


F = 9a2 + 24a + 16

F = ..................................................................

F = ..................................................................


Factoriser les expressions suivantes :

A = 9p2 + 30 p + 25

B = s2 + 36 – 12s

C = 1 – e2

bonjour,

A = ( 2 z + 3 )²

b  = ( 4 r - 5 )²

c =  ( 3 t - 8 ) ( 3 t + 8 )

d = ( 5 y - 7 )²

e = ( d - 4 ) ( d + 4 )

f =  ( 3 a + 4 )²

--------------------------------------------------------------------------------------------

a =  ( 3 p + 5 )²

b = ( s - 6 )²

c = ( 1 - e ) ( 1 + e)
