    It's a "typo." I read x = -3/5 instead of x = -3/4. Sorry!

    no worries!

    i was also wondering whether to test the minimum using the idea that as
    x goes of to infinity the objective becomes arbitrily large. can you actually use this concept to test for a minimum value?!

    and is there a better way using a second derivative and plugging the numbers in, and if so how would it work?
