    as you can see up there Sam chick thinks it's D but I wasn't sure if he was right so, from the way you asked me i'm taking it that D is wrong and my answer is C am I right? @Hero

    So basically, you admit that you did not use any strategy to come up with D, which means you're essentially guessing, which is okay because we've all guessed at one point or another.

    But, here's a bit of information that can help you out: For a polynomial of the form \(ax^2 + bx + c\), the expression is factorable if \(b^2 = 4ac\) is a perfect square. Otherwise, it is prime.

    So, basically, your first step is to figure out whether \(b^2 - 4ac\) is factorable first before doing anything else.

    Sorry \(b^2 - 4ac\) not \(b^2 = 4ac\)
