Answer:

= 9x² - 8

Step-by-step explanation:

9x² - [4x² - {3x² + 2x - 8 + (x² - 2x)}]

= 9x² - [4x² - {3x² + 2x - 8 + x² - 2x}]

= 9x² - [4x² - {3x² + x² - 2x + 2x - 8 }]

= 9x² - [4x² - 4x² - 8 ]

= 9x² - 8

Answer:

Step-by-step explanation:

Answer:

= 9x² - 8

9x² - [4x² - (3x² + 2x - 8+ (x² - 2x)}] = 9x² - [4x² - (3x² + 2x -8 + x² - 2x}]

= 9x² - [4x² - (3x² + x² - 2x + 2x - 8 }] =

= 9x2-[4x²-4x2-8]

= 9x² - 8
