How do you know when a solution is extraneous?
When you plug in the solution, there is 0 in a numerator.
When you plug in the solution, there is 0 in a denominator.
When the solution is x = 0
It looks extra. 💁♀️
Answer explanation
We are not allowed to divide by 0! So when there's a 0 in the denominator after substituting it in, the solution is extraneous.
