Given that P(x) and Q(x) are polynomials, the following equalities hold:

[ P(x-1) = (x-3)(2x+k) ]

[ P(x+1) = x*Q(x-1) ]

What is the value of Q(4) according to this information?

yes

I found the roots of the polynomial P(x-1) as 3 and 2, in this case K is 4, but I could not continue.

#

P(x-1)= (x-3)(x-2)
