1. (x - ___)3 = ___ - ___ + ___ - 27

2. ( 2X + ___ )3 = ___ + ___ + ___ +27y3

3. (x - y)3 = x3- 3x2y + 3xy2 –y2

4. ( ___ + ___ )3 = 8m3 + 12m2 + ___ +___

5. (5 X - ___ )3 = ___ - ___ + ___ -64y3

6. ( ___ - ___ )3 = 125 – 75X + 15X2 –X3

7. ( ___ - ___ )3 = 8m3n3- ___ + ___ - 1

8. (4 X - ___ )3 = ___ - ___ + ___ - 125

Answer 1

Explicación paso a paso:

1. (x - 3)³ = x³ - 9x +27x - 27

2. ( 2X + 3 )³ = 8x³ + 36x²+ 54x +27y³

3. (x - y)³ = x³- 3x²y + 3xy² – y³

4. ( 2m + 1 )³ = 8m³ + 12m² + 6m + 1

5. (5x - 4y )³ = 125x³ - 300x²y + 240xy² -64y³

6. (5 - x )³ = 125 – 75X + 15X² –X³

7. ( 2mn- 1 )3 = 8m³n³- 12m²n² + 6mn - 1

8. (4x - 5)3 = 64x³ - 240x² + 300x - 125
