Answer:
- 45x² - 12x - 14
Step-by-step explanation:
- 2 + 8x - { 5x [ 2x - ( 2 - 7x ) + 8 ] - 6x } - { 5 - ( 4x - 7 ) } =
- 2 + 8x - 5x [ 2x - ( 2 - 7x ) + 8 ] + 6x - 5 + ( 4x - 7 ) =
- 2 + 8x - 5x [ 2x - 2 + 7x + 8 ] + 6x - 5 + 4x - 7 =
- 2 + 8x - 10x² + 10x - 35x² - 40x + 6x - 5 + 4x - 7 =
- 45x² - 12x - 14
