Hi all,

I was working a quadratic factor problem, but only managed to solve B and C. Attached is my working.
Can anyone please tell my how to solve the rest (i.e. A and D).

You've still to equate coefficients of $x^{3}$ and $x.$

but for x^3 there will be 2 unknowns (A and D) and x have no coefficients, if I'm working good.

$x: \quad 5 = 5A.$
