EXPLANATION:-

For numerator We expanded by formula of

(a-b)³ = a³-b³ -3ab(a-b)

After expansion ,

We can simplify the numerator

After simplification of numerator

Take common 3

After we can get a equation

We can simplify by the formula of

a²-b² = (a+b)(a-b)

We can get a equation

According to that equation We have to simplify By using According to the Question data

a² + b² + c² = 0 => Given So,

• a² + b² = -c²
• a² + c² = -b²
• b² + c² = -a²

Substitute these values in numerator and take a common -a²b²c² After taking this The entire numerator gets converted interms of denominator .So , both cancelled each other . -a²b²c² Remains in the numerator

So, the answer is -a²b²c² [b]
