Answer 1

Answer:

ur first answer is 10ab 4

Answer 2

Answer:

1. 5a² + 5 b²

 = 5(a² + b²)

2. 2a² + 3ab

 = a(2a+ 3b)

3. 8x²y - 24x²y²

  = 8x²y(1 - 3 y)

4. 7a² - 14ab + 21a

  = 7a ( a - 2b + 3a)

  = 7a ( a( 1 - 3) - 2b)

5. 3ab² + 15a²b² + 21a³b²

  = 3ab²(1 + a(5 + 7a))

6. 6a(3x - 5y) - 3a² (3x - 5y)

   = (6a - 3a²)(3x - 5y)

hope it helps.

BTW which textbook is that?
