I = 10 z³
M=-3(-6m)_12+m*(-3m)+4-17m
M = 18 m - 12 - 3 m² + 4 - 17 m
M = - 3 m² + m - 8

N = 12 t² - 3 + 10 t - 12
N = 12 t² + 7 t - 12

Bonjour,
l=z*(-2)*z*(-5)*z
= 10z³
M=-3(-6m)-12+m*(-3m)+4-17m
= 18m -12 -3m² +4-17m
= -3m² +m -8
N=4t*(3xt)+(-3)+5*2t+6*(-2)
= 12xt² -3 +10t -12
= 12xt² +10t -15
O=(9f+8)-(15-4f)
= 9f+8-15+4f
= 13f -7
