svp pouvez vous factoriser : a-x²-2x+1 b- x²+10x+25 c-9x²-24x+16 d-64x²-25 e-y²-1 f-16-y² g-y²-36 svp répondez vite c'est un devoir très important pour ma

Bjr

A = x²-2x+1

A = x²-2×x×1+1²

A = (x-1)²

B = x²+10x+25

B = x²+2×x×5+5²

B = (x+5)²

C = 9x²-24x+16

C = 3²x²-2×3x×4+4²

C = (3x)²-2×3x×4+4²

C = (3x-4)²

D = 64x²-25

D = 8²x²-5²

D = (8x)²-5²

D = (8x-5)×(8x+5)

E = y²-1

E = y²-1²

E = (y-1)×(y+1)

F = 16-y²

F = 4²-y²

F = (4-y)×(4+y)

G = y²-36

G = y²-6²

G = (y-6)×(y+6)
