Step-by-step explanation:
What you would need to do is find the square root of one hundred and twenty one [what number multiplies by itself to get one hundred and twenty one].
The answer would be eleven. HOWEVER, it could be both a positive and a negative, minus eleven times minus eleven is positive one hundred and twenty one. When you times two negatives, the answer becomes positive.
I hope this helps.
Answer = negative eleven and positive eleven
