    As an example:
    X^2 + x^2 = 2x^2
    X^2 × x^2 = x^4
    -2x - 2x = -4x
    I think this is where you're going wrong...

    As far as I know, yes. You just need to change that to what you just worked out rn.
    Though my maths is quite rough, so I wouldn't rely on me.

    edit, wait looks like I got this wrong. idk now

    1d incorrect - check your pluses and minuses again: `-3x + 2y - 5x + 7y`.

    4a, 4b, and 4c are also incorrect, so I recommend you work on your multiplying out brackets. I recommend using a grid for it - I'll attach an image of what I mean (if I work out how to, I literally just made an account).

    All of 2 and 5 look correct, though, so you're doing pretty well on that front c:
