Answer 3

Expand both the numerator and denominator.
numerator: (u - 2)(u + 2)
denominator: u(u - 2u)
From here you can cancel out (u-2) to get:
\[(u + 2) \div u\]
The "u"s cancel out to get:
\[2 \div u\]

Answer 4

A.
u+ 2, u ≠ 2

B.

MU2d.gif u ≠ 2


C.

MU2b.gif u ≠ 2, u ≠ 0


D.

MU2a.gif u ≠ 0

Answer 5

Oh that's finding the restrictions, not simplifying. Also, I totally simplified it wrong so don't look at that. xD

Again, just set the denominator equal to 0.
The answer would be C.

You can also plug in each answer into the denominator to check.
