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
