Reactions
gollark: It wants something in terms of p and q, so just simplify it a bit.
gollark: Although I don't know why you can't long-divide it, p and q are just constants for the purposes of that.
gollark: That lets you work out a/b/c/d, which you can substitute back into (x-1)(ax^3+bx^2+cx+d).
gollark: So:2 = a (x^4 terms)p = b - a (x^3 terms)-6 = c - b (x^2 terms)q = d - c (x terms)6 = -d (constant terms)
gollark: So you can do `2x^4+ px^3 - 6x^2 + qx + 6 = ax^4 + (b-a)x^3 + (c-b)x^2 + (d-c)x - d`, and you know the coefficients on x^4 and so on should be equal.
