Question

# Why does solving a radical equation sometimes result in an extraneous solution?

Hint:

### Write the reason.

## The correct answer is: non-invertible

**Complete step by step solution:**

Sometimes when we perform non-invertible operation on both sides of the equation,

then an extraneous solution arises. For example, squaring is an non-invertible

operation.
