hi!!!!! Um, I did the math, and I hope
i'm right! Let me know if i'm
not......The first answer is this:
4y + 1 =
5y squared
second answer was a little more tricky bc
I couldn't tell if the 3x was supposed to
be divided by x squared or not bc / is
also a sign to divide, and you had
3x/xsquared, so I just ignored
the second (bolded) x and did the math
like it read 1/x-1 - 1/x+1 =
3xsquared-1
1=3xsquared

I think the second one is supposed to be
divided where the slash is.
But hey, I thought i'd let you guys in on
some math lingo. If you wanna express a
number as "squared" or to the power of
another number you would express it as
such..
2^2 - two squared
4x^4 - 4x to the power of 4
5^24 - 5 to the power of 24
get it?
