    Factor completely 8m^3 - 12m^2 + 4m. I got 4 (2m^3 - 3m^2 + m)

    well, first step, you should try factoring it out.

    lets see: \(\large\color{slate}{\displaystyle \sqrt{(-3)^2-4\cdot2\cdot1}=\sqrt{9-8}=\sqrt{1}=1}\)

    you're on the right track but you're not quite done yet notice how each of the terms in the parantheses still has m, right? you can factor out m

    yeah, your are not done. You can factor it more. (What I did just now, is the discriminant test)

    factor out 4m instead of 4.

    factor out of 4m, and even then not done

    Alright. I got 4m (2m^2 - 3m) is this correct?

    and as I demostrated with discriminant test, it is factorable

    2m^2-3m+1 => 2m^2-2m-m+1

    Alright, alright alright. Listen guys, I'm really getting overwhelmed with all of you trying to help. I appreciate you guys trying to help but I can't focus on so many people. So, I will focus on Solomon since he was the first to respond on this post. Sorry

    now, look at 2m^2-3m+1 alone. you can factor it, and I will give you a hint: re-write it as 2m^2-2m-m+1

    Pro tip. It is easier to look at when the coefficients are positive.

    You can take two negatives out..... it is a little bit strange to me the way you wrote it. What I meant to see was rather. \(\large 2m^2-3m+1\) \(\large 2m^2-2m-m+1\) \(\large 2m(m-1)-m+1\) \(\large 2m(m-1)-1(m-1)\) \(\large \color{red}{2m}(m-1)+\color{red}{-1}(m-1)\) \(\large (2m-1)(m-1)\)

    I mean the way you did it is perfectly fine. As long as it is correct. But I am just letting you know my point of view from the side.

    it's just easier to manage without negative coefficients... nobody likes negative XD

    Alright, but the answer (2m-1) (m-1) isn't an option. Well, there is. But, there is a 4m in front of it. 4m(2m - 1) (m - 1)

  36. SolomonZelman

    yes, because you are factoring 4m(2m^2-3m+1)

  37. SolomonZelman

    you are not factoring just the 2m^2-3m+1 I took a look at it alone, so that we can factor it, but the 4m does't go away.

    Alright. Thanks guys! And Plasma, the options are 2m (4m2 - 6m + 2) 4 (2m3 - 3m2 + m) 4m (2m - 1)(m - 1) 4m (2m2 - 3m)
