Question

# Prove the sum of cubes identity :

Hint:

### where a, b, c and d are real numbers. We are asked to prove the given equation.

## The correct answer is: Hence, the proof

Explanation:

The given equation is The LHS and RHS are a^{3} + b^{3}

and respectively.

We have to prove they are equal. For that prove the LHS and the RHS are equal.

Step 2 of 2: Multiply the RHS in the given equation,

Hence, the proof.

To prove an equation to be equal, we have to prove either the RHS is equal to the LHS or vice versa. The side should be selected based on the simplification process.
