Learn French: Je ne trouve pas la colle, tu peux m'aider ? - I cannot find the glue, can you help me?

When you have a conjugated verb followed by an infinitive (like peux + aider), the object pronoun goes immediately before the infinitive it belongs to. Since the action being done to you is helping, the pronoun m' (me) goes right before aider (to help).

Why is it m'aider and not me aider?

The object pronoun me drops its e and adds an apostrophe because the next word, aider, starts with a vowel. This makes it flow better when speaking.

The English translation says "I cannot find", but there is no word for "cannot" in the first half of the French sentence. Why?

In English, we often say "I can't find" or "I can't see". In French, it is more natural to just use the standard negative present tense for these actions. Je ne trouve pas literally means "I do not find", which carries the exact same meaning in this context.

Why does the question part say tu peux m'aider ? instead of peux-tu m'aider ?

Tu peux m'aider ? keeps the normal word order but becomes a question by raising your voice at the end. This is the most common and natural way to ask questions in everyday spoken French. Reversing the verb and subject (peux-tu) is perfectly correct but sounds a bit more formal.
