Question

dati factor comun in urmatoarele expresii:
3x+5x-2x
12a-16b
18x-12z+24t
9x+9y+9z-9a
5x+10y-15a
18a-27b
8xy-8xz
3xa+5xa-2xa.

Answer 1

3x+5x-2x=x(3+5-2)=6x
12a-16b=4(3a+4b)
18x-12z+24t =6(3x-2z+4t)
9x+9y+9z-9a =9(x+y+z-a)
5x+10y-15a=5(x+2y-3a)
18a-27b=9(2a-3b)
8xy-8xz=8x(y-z)
3xa+5xa-2xa=xa(3+5-2)=6xa

Answer 2

12a-16b=4(3a-4b)
3x+5x-2x=X(3+5-2)=6X

18x-12z+24t=6(3x-2z+4t)


9x+9y+9z-9a=9(x+y+z-a)

5x+10y-15a=5(x+2y-3a)
18a-27b=9(2a-3b)

8xy-8xz=8x(y-z)
3xa+5xa-2xa.=xa(3+5-2)=xa*6=6xa
