bonjour je dois factoriser
P= 4x+8
Q=17d-13d
R=21v+9vt
S=12s-6
T=-2t(au carré) +4t
( niveau 4ème)
Merci☺️​

bjr

P = 4 * x + 4 * 2 = 4 (x + 2)

Q = d * 17 - d * 13 = 4d

R = 3v * 7 + 3v * 3t = 3v (7 + 3t)

S = 6 * 2s - 6 * 1 = 6 ( ... - ...)

et T = -2t² + 4t = 2t * (-2) + 2t * 2 = 2t (... + ...)

:)
