Question

B

`b {?}^(3 ) - c {?}^(3)`
​

Answer 1

`b^3-c^3=(b-c)(b^2+c^2+bc)`

Step-by-step explanation:

We need to write the value of
`b ^(3 ) - c ^3`. It is a well known identity of algebra.

`b^3-c^3=(b-c)(b^2+c^2+bc)`

Here,

b and c are any number.

We know that,

b² = b×b

bc = b × c

Hence, this is the required solution.
