Answer 1

hey what a hell is this i think the above man is correct

but still apply binomial theorem to do thes e

Answer 2

These are a FEW questions? Looks to me like someone was out playing all weekend instead of taking care of business. Here's a hint. Use Pascal's Triangle. It makes things much easier to work out. Also, make sure you do the indicated division for the needed term whenever there is a fraction involved, unless your teacher doesn't want you to divide it out. Otherwise, your coefficients and/or variable powers can get all screwed up.

Answer 3

The idea of an education is to learn. I see no way that you are learning this way by asking for the answers. Though it may make some of the people on Yahoo Answers smarter I am going to suggest that you earn your own passing D on your own.
