Question

12x-(3x3+5×2-(7×2-(4-3×-×3)+6×)-3×)

Answer 1

Answer:

12x - [3x³ + 5x² - {7x² - (4 − 3x − x³) + 6x³} -

- 3x] We will first remove the innermost grouping symbol (), followed by {} and then [].

12x - [3x³ + 5x² - {7x² - (4 - 3x - x³) +

6x³} - 3x]

= 12x - [3x³ + 5x² - {7x² − 4 + 3x + x³+ 6x³}

- 3x]

= 12x - [3x³ + 5x² - {7x² - 4 + 3x + 7x³} -

3x]

12x − [3x³ + 5x² - 7x² + 4-3x - 7x³ - 3x]

= 12x [2x2 + 4 - 4x³ - 6x]

= 12x + 2x² - 4 + 4x³ + 6x
