    Every polynomial with real coefficients factors into linear and quadratic terms.

    How much machinery is needed to show this?

    If it crosses the X-axis then it has a linear term.

    If it doesn't cross the X-axis then it is of even degree, and the roots come in complex conjugate pairs.

    What the minimum needed to see this?

    I've been thinking about this for ages, but never had the time to craft the words around it.

    People keep saying that "Maths should be fun" ... and I push back with "It should be engaging ... 'fun' is a different thing.

    So @rakhichawla has posted pretty much exactly this, but better than I ever could.

    I'm copying it here with permission.

    Please read this, then as it says at the end ... let's have a deeper conversation about this ...

    1/n

    (PS: I'd love this to get boosted to get outside my bubble ... you're all amazing, but there will be other opinions, and other thoughts that could be helpful or valuable)

    Fermat conjectured that for \(n\) a non-negative integer, all numbers of the form \(2^{2^n}+1\) are prime.

    Was there ever a worse conjecture in maths than that?

    Some time ago ... (A month!) ... there was a thread on Twitter that I think should be shared here. I've been trying to extract and post it semi-automatically, but Twitter just makes it damn near impossible.

    So I'm copying it "by hand"

    Here's a chart of the full conversation:
