Question

# Prove the difference 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

### Step 1 of 2:

The given equation is This can be proved by multiplying the RHS of the equation and simplifying to form the LHS.

Step 2 of 2:

Multiply the RHS in the given equation,

Hence, the proof.

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.
