Bantuin dong 1-10 makasi banyakkk

*note: sebisanya aja gapapa*

Answer 1

1. 6a + 8ab = 14ab

2.
3. 3a + 6b + 24c = 3a6b24c

4.
5.
6.
7.
8. 3x^4 - 243 = 3(x^4 - 81)

9. (m-n)^2 - 1 =
   (m-n) (m-n) -1
   m^2 - mn - mn - n^2 - 1
   m^2 - 2mn - n^2 - 1

10. 4(x-y)^2 - (x+y)^2 =
       4(x-y) (x-y) - (x+y) (x+y)
       4(x^2-xy-xy-y^2) - x^2 +xy + xy + y^2
       4(x^2 - 2xy - y^2) - x^2 + 2xy + y^2
       4x^2 - 8xy - 4y^2 - x^2 +2xy + y^2
       2x^2 - 6xy - 3y^2
