1nn - 11mn=

a² -7ab² -5b²=

3a + 5a -10a =

6/8a + 2/4b + 1/6a - 1/8b=

4x - 3x - 2x=

7ab + 4ab - 3ab =

5a² - 7a² + 3a² - 2a² =

0.25b - 0.4b + 0.2b. =​

Answer 1

6xy² - 1xy² - 3xy² = 2xy²

1nn - 11mn= n×(n-11m)

a² -7ab² -5ab²= a×(a-12b²)

3a + 5a -10a = -2a

6/8a + 2/4b + 1/6a - 1/8b= 1/24 × (22a + 9b)

4x - 3x - 2x= -x (-1x)

7ab + 4ab - 3ab = 8ab

5a² - 7a² + 3a² - 2a² = -a²

0.25b - 0.4b + 0.2b. = 0,05b
