Bonjour,Factorise puis réduis ces expressions
5x+4x
= x (5 + 4)
= x (9)
= 9x
9x-2x
= x (9 - 2)
= x (7)
= 7x
6x+x
= x (6 + 1)
= x (7)
= 7x
2x+7x-5x
= x (2 + 7 - 5)
= x (9 - 5
= x (4)
= 4x
8xy-7xy
= xy (8 - 7)
= xy (1)
= xy
18z² -9z² +3z²
= z² (18 - 9 + 3)
= z² (21 - 9)
= z² (12)
= 12z²
A³+ A³ + A³
= a³ (3)
= 3a³
1/2x+1/2x
= 1/2x (2)
= 2/2x
= x
5ab-9ab+ab
= ab (5 - 9 + 1)
= ab (6 - 9)
= ab (- 3)
= - 3ab
