Answer 1

Answer:

          (a)  a = b = c

(This is assuming that a, b, c are supposed to be real numbers!)

Step-by-step explanation:

x³ + 3x² + 3x + 2  =  (x + 2)(x² + x + 1)

As x²+x+1 has complex conjugate roots, and the coefficients a,b,c are supposed to be real, the two common roots cannot be -2 and one of these complex roots.  So they must be these two complex conjugate roots.  It follows that ax²+bx+c = a(x²+x+1), so a=b=c.
