\n" ); document.write( "The polynomial of degree 3, P(x) has a root of multiplicity 2 at x=2 and a root of multiplicity 1 at x=−5.The y-intercept is y=−8 Find a formula for P(x).

\n" ); document.write( "The polynomial in factored form is

\n" ); document.write( "\"P%28x%29+=+a%28x-2%29%5E2%28x%2B5%29\"

\n" ); document.write( "To find the coefficient a, use the fact that the y-intercept is -8 -- i.e., that f(0) = -8:

\n" ); document.write( "\"-8+=+a%28-2%29%5E2%285%29\"
\n" ); document.write( "\"-8+=+20a\"
\n" ); document.write( "\"a+=+-2%2F5\"
