20 points m factor the polynomial function over the complex numbers. f(x) = x^4 + 9x^3 + 15x^2 + 9x + 14 enter your answer in the box.

its actually 10 points

x^4 + 9x^3 + 15x^2 + 9x + 14

Split  15x^2  into  14x^2  +  x^2

x^4 + 9x^3 + 14x^2 + x^2 + 9x + 14     factor as

x^2  [x^2 + 9x + 14 ]  +  1 [ x^2 + 9x + 14 ]   take out GCF

[ x^2 + 1 ] [ x^2 + 9x + 14 ]

[ x^2 + 1 ] [  x + 7 ] [ x + 2 ]
