(1) If f(x)= ax³–9x²+bx+12 has x+1 and 2x–3 as factors, then find the values of a and b (without using the actual process of Division of Polynomials).

(2) If (x²–4x+3) is a factor of cx⁴+dx³–13x²–14x+24, then find the values of c and d (without using the actual process of Division of Polynomials).

1) a=2
    b=1

2) c=1
    d=2

All I did was use algebra, set missing numbers as variables, and started setting things equal to each other. That's what I got.
