Question

(-14b³ - 9a²b4 - 12b²) - (4a²b^4 - 14b³ + 11b)

my answer is wrong ​

Answer 1

$\LARGE{\sf{\underline{\underline{Solution:-}}}}$

(-14b³ - 9a²b⁴ - 12b²) - (4a²b⁴ - 14b³ + 11b)

• As there is a - sign, the signs of the values under brackets will change.

= - 14b³ - 9a²b⁴ - 12b² - 4a²b⁴ + 14b³ - 11b

• Now, place the like terms together.

= - 14b³ + 14b³ - 9a²b⁴ - 4a²b⁴ - 12b² - 11b

• - 14b³ and 14b³ will cancel.

= - 9a²b⁴ - 4a²b⁴ - 12b² - 11b

= - 13a²b⁴ - 12b² - 11b

• Now, no more calculation, as there are unlike terms.

$\LARGE{\sf{\underline{\underline{Required \ Answer:-}}}}$

- 13a²b⁴ - 12b² - 11b
