    You mixed up the answers for question 2. Re-read your answers for question 2.

    wait so it'd be 3, multiplicity 2; 5, multiplicity 2? @Azteck

    Go by what you did in question 1. If what you wrote just now matches what you did in question 1, then you know it's correct.

    Your new answer is correct, you switched the zeroes and the multiplicity for question 2 in your original answer.

    So they are both correct now? @TimSmit

    Dude, be confident of what you put. Being dependent on us strangers rather than feeling that the answer is correct means you're not confident at all.

    They are correct :) but as azteck says, you came close to the solution yourself which shows you understand, but mixed two numbers, it happens.
