Answer 1

1. 8x + 49
2. 4x + 121
3. 25/6 + 64 —— en esta no estoy segura sorry

Answer 2

Explicación paso a paso:

1. (4x + 7)²

  =16x²+2(4)(7)x+49

  = 16x²+56x+49

2. (2x + 11)²

  = 4x²+2(2)(11)x+121

  = 4x²+44x+121

3. (5/6m + 8)²

   = 25/36m²+2(5/6)(8)m+64

   = 25/36m²+40/3m+64

4. (6X-9) (6X+9)

   = 36x²+54x-54x-81

  = 36x²-81
