    Factorize, sorry. I am supposed to factorize this polynomial -

    What do you think the first step should be?

    I know what the first step is, I think. I'm supposed to find the GCF of the whole thing.

    Sorry.. there are FOUR terms, so you were correct. First find the GCF :)

    No problem :) So, I need to split the middle term? I'm not sure how I should do that.

    You will learn that later on :) This is a factoring by grouping problem.

    What do you think the GCF of this polynomial is?

    Okay, so this is where I am having the problem. I know how to factorize by grouping, but for this particular problem I am stuck on how to find the gcf.

    The GCF is negative q. Reason why is because it is used in all terms. Sometimes you have special cases like these that the sign won't always correspond with the problem.

    You got it from here? I can verify your answer once you're done :)

    I think so. I got an answer of \[q(p+r - pqr)\]

    So close! You mixed up your signs a bit

    Awesome! Love to see that from the ones I help. I love factoring.. once you get the hang of it, it'll flow out just like water. :)
