im having trouble re-writing things in the sign basis, please can someone give a step by step solution to the following problem:

Let |ϕ⟩=12|0⟩+1+2√i2|1⟩. Write |ϕ⟩ in the form α0|+⟩+α1|−⟩. What is α0?

Thanks.

Hi Daniel, and welcome to Physics Stack Exchange! This is a site for conceptual questions about physics, not general homework help. If you can edit your question to ask about the specific physics concept that is giving you trouble (e.g. think about why you are unable to solve this problem, don't just ask for a solution), I'll be happy to reopen it. See our FAQ and homework policy for more information. – David Zaslavsky♦ Jul 23 '12 at 17:24

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
