Question

factorise a minus b minus A cube plus b cube​

Answer 1

The factors of the given expression are (a - b) and (1 - a² - ab - b²).

Step-by-step explanation:

Consider the provided expression.

a - b - a³ + b³

The above expression can be written as:

= (a - b) - (a³ - b³)

Now use the formula:  x³-y³=(x-y)(x²+xy+y²)

= (a - b) - [(a - b)(a² + ab + b²)]

Take a-b common.

= (a - b)[1 - (a² + ab + b²)]

= (a - b)(1 - a² - ab - b²)

Hence, the factors of the given expression are (a - b) and (1 - a² - ab - b²).
