    factoring

    Ive noticed this a couple of times in my math book. 2t^2 + 6t + 6 is factored as 2(t^2+ 3t + 3)

    If that is the case why would it be incorrect to factor 2x^2 + 10x + 12 as 2(x^2 + 5x + 6)?

    It is not incorrect.

    As far as I know that isn't incorrect. It looks fine

    So 2x^2 + 10x + 12 can be either 2(x^2 + 5x + 6) or 2(x + 3)(x + 2)?

    If you analyse this : x^2 + 5x + 6 more yes you do get (x + 3)(x + 2) and you also have the 2 from before so, yes.

    Thanks for the help. At least i have a valid arguement to present to my teacher if the factored expression is marked wrong for some reason.

    BTW, in school they usually ask you to completely factor an expression, so 2(x + 3)(x + 2) is the only right answer...
    You just proved that sig advertisements work.
