bonjour

7 x - 14  = 7 ( x - 2 )

12 t + 6 = 6 ( 2 t + 1 )

a² + 3 a = a ( a + 3 )

4 b² - 12 = 4 ( b² - 3 )

2 t² - 3 t = t ( 2 t - 3 )

4 x² + 20 x = 4 x ( x + 5 )

- 5 x² + 25 x =  - 5 x ( x  -  5)

- 10 - 16 a =  - 2 ( 5 + 8 a)  

INEQUATION

Bonsoir,

Factoriser chaque expression:

A= 7(x-2)            B= 6(2t+1)

A= a(a+3)           B= 4(b²-3)

A= t(2t-3)           B= 4x(x+5)

A= -5x(x-5)        B= -2(5+8a)
