Answer 2

wtf. its like rocket science. im doing this for homework too

Answer 3

If you look at the first question. Before you even start x cannot be -3, otherwise you are dividing through by 0.
So if in solving the answer turns out to be -3, you have to exclude it.

In the second one, when solving, you will have to divide by (a - b).
so clearly a cannot have the same value as b.
If it did then c must equal 0.

Answer 4

I got the same questions for homework too. I have no clue how to do it.
