Learn Turkish: Yeni bir anlaşma imzalamanız mümkün mü? - Is it possible for you to sign a new agreement?

This word is formed from the verb stem imzala- (sign), the short verbal noun suffix -ma, and the plural/formal 'your' possessive suffix -nız. Literally, it means 'your signing'. In Turkish, to say 'is it possible for you to do X', you make the action the subject of the sentence by turning it into a noun. The sentence literally asks: 'Is your signing a new agreement possible?'

Both anlaşma and imzalamanız end with -ma. Are they doing the same grammatical job here?

Historically, yes, but in practice, no. Anlaşma (agreement) has become a permanent, fixed dictionary noun. You just treat it like any standard object. On the other hand, imzalamanız uses the -mA suffix actively to turn a verb into a noun for this specific sentence, allowing it to take the possessive ending -nız to show who is doing the action.

Could I just use the infinitive imzalamak instead of imzalamanız?

You could, but it would change the meaning. If you use the full infinitive imzalamak, the sentence becomes a general statement: Yeni bir anlaşma imzalamak mümkün mü? (Is it possible to sign a new agreement?). By using the short verbal noun with a possessive ending (imzalamanız), you specifically ask if it's possible for you to do it.

Where is the word for 'you' or 'your' in this sentence?
