Sagot :
bonjour
A = 8 m - 32
B = 36 p + 72
C = - 8 m + 10
D = 45 + 5 m
E = 7 m + m² + 35 + 5 m
= m ² + 12 m + 35
F = 63 m² - 63 m + 35 m - 35
= 63 m² - 28 m - 35
G = 4 y - 18 + 12 y + 4 y - 4
G = 20 y - 22
H = 56 m² - 7 m - 32 m + 4
H = 56 m² - 39 m + 4
Bonjour,
Développer et réduire les expressions suivantes :
A= 8(m-4)
A = 8m - 32
B= 9(4p+8)
B = 36p + 72
C= -2(4m-5)
C = - 8m + 10
D= -5(-9-m)
D = 45 + 5m
E= (m+5) (7+m)
E = m² + 7m + 5m + 35
E = m² + 12m + 35
F= (9m+5) (7m-7)
F = 63m² - 63m + 35m - 35
F = 63m² - 28m - 35
G= 4y-6(3-2y) +4(y-1)
G = 4y - 18 + 12y + 4y - 4
G = 20y - 22
H= (7m-4) (8m-1)
H = 56m² - 7m - 32m + 4
H = 56m² - 39m + 4.
