$$144h ^{2}-169z ^{2}$$

anonymous · Answer

what is the easiest way to find out what the square of 144 and 169 is?????How do I go about finding the square of a number???

anonymous · Answer

you can use a calculator, but it's pretty much memorization in my opinion... so what number when multiplied by itself gets 144?

anonymous · Answer

and what number times itself gets 169?

anonymous · Answer

once you figure that out, then there you go! you've found the square of a number :)

anonymous · Answer

example: factor 16. 4 x 4=16, so the square of 16 is 4

anonymous · Answer

12 and 13.

anonymous · Answer
