    I've never seen it done this way before!

    I just find two numbers that add to make b and multiply to make c, which I guess is just a shortcut version of this really...

    Just needed help on these questions and if someone can check if i did them correctly thank you so much ♡ image is below X
    Nice! I don't know this method to factorise quadratic terms. You made it very good. However, one step in your second equation isn't right.

    x^2 - x - 12 = 0 <=> x^2 -4x -3x - 12 = 0

    You have choosen the wrong sign: -4x -3x = -7x, that is not equal to -x.

    It has to be: -4 + 3x = -x

    For Gcses we show the full working out. So if the answer isn't correct at least we get a few marks for the working out!

    No, I have to thank you, really!

    I have never seen such steps to solve factorising issues before. You have shown me a good alternative to factorise terms. It facilitates this calculation so much. A great thank you to you.

    Exactly, I think the problem OP has is confidence or something, because I've never seen someone do that much working out. And I agree, you can do most things very quickly in your head.
