The polynomial of degree 3, P(x) has a root of multiplicity 2 at x=4 and a root of multiplicity 1 at x=−4, The y-intercept is y=−51.2. Find a formula for P(x).
\n" ); document.write( "-----
\n" ); document.write( "P(x) = A(x-4)^2(x+4)
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"A\" using (0,-51.2)
\n" ); document.write( "-----
\n" ); document.write( "P(0) = -51.2
\n" ); document.write( "-51.2 = A(0-4)^2(0+4)
\n" ); document.write( "-51.2 = A*16*4
\n" ); document.write( "-51.2 = A*64
\n" ); document.write( "A = -51.2/64
\n" ); document.write( "---------------------
\n" ); document.write( "Ans: P(x) = (-51.2/64)(x-4)^2(x+4)
