The polynomial of degree 4, P(x) has a root of multiplicity 2 at x=2 and roots of multiplicity 1 at x=0 and x=−2. It goes through the point (5,252).
Find a formula for P(x).
----------------------------------------------------------------------

According to the given information about the roots,  the polynomial is

P(x) =   =           (1)

with some unknown real coefficient  .

To find  ,  use the fact that the plot of the polynomial goes through the point  (5,252).  It means that  P(5) = 252.
So,  simply substitute  x=5  into the polynomial  (1). You will get the equation

= ,     or

= ,       or

= .

Hence,   = = .

Therefore,  P(x) = ..

You can open the parentheses if you need.
