Answer 1

Respuesta:

1.  12x5 - 7x3 + 9x - 1

2. 9x - 1

3.  4x4 + 6x3 + 6x2 + 10x + 2

4.  10x3 + 3x2 + 11x - 3

Explicación paso a paso:

1. (5x5 – 2x3 + 5x – 4) + (3 + 4x - 5x3 + 7x5) = 12x5 - 7x3 + 9x - 1

2. (5x – 4) + (3 + 4x) = 9x - 1

3. (4x4 + 6x2 + 5x - 5) + (6x3 + 5x + 7) = 4x4 + 6x3 + 6x2 + 10x + 2

4. (7x3 – 2x2 + 4x - 1) + (3x3 + 5x2 + 7x - 2) =​ 10x3 + 3x2 + 11x - 3
