You can put this solution on YOUR website!
a. what is the inverse of squaring a number?
It's finding the square root, the number that when squared gives the result. As in part b of your post.
------------------------------
b. the principal square root of 144 is 12. what is the other square root of 144?
It's -12
12*12 = 144
(-12)*(-12) = 144
-------------------
There are always 2 square roots.
