6mm-9n =

4ab + 4b =

12-9+ 21=

Answer 1

2a-8 = 2(a-4)

 

25x-15=5(5x-3)

 

18y+27=9(2y+3)

 

45ab²-9a²b=9ab(5b-a)

 

3y²+6y-9=3(y²+2y-3)

 

6mm-9n=3(2mm-3n)

 

4ab+4b=4b(a+1)

 

12m³n²-9m²n⁴+21m⁴n³=3m²n²(4m-3n²+7m²n)

Answer 2

2a-8=2(a-4)

25x-15=5(5x-3)

18y+27=9(2y+3)

45ab^2-9a^2b=9ab(5b-a)

3y^2+6y-9=3(y^2+2y-3)

6mn-9n=3n(3m-3)

4ab+4b=4b(a+1)

12m^3n^2-9m^2n^4+21m^4n^3= 3m^2n^2(4mn-3n^2+7m^2n)
