Factor the trinomial x2n−5xn−36x ^ { 2 n } - 5 x ^ { n } - 36x2n−5xn−36 . (Assume that n represents a positive integer.)
A) (xn−9) (xn−4) \left( x ^ { n } - 9 \right) \left( x ^ { n } - 4 \right) (xn−9) (xn−4)
B) (x2n−9) (x2n+4) \left( x ^ { 2 n } - 9 \right) \left( x ^ { 2 n } + 4 \right) (x2n−9) (x2n+4)
C) (xn−9) (xn+4) \left( x ^ { n } - 9 \right) \left( x ^ { n } + 4 \right) (xn−9) (xn+4)
D) (x2n+9) (x2n−4) \left( x ^ { 2 n } + 9 \right) \left( x ^ { 2 n } - 4 \right) (x2n+9) (x2n−4)
E) (xn+9) (xn−4) \left( x ^ { n } + 9 \right) \left( x ^ { n } - 4 \right) (xn+9) (xn−4)
Trinomial
A polynomial with three terms, often expressed in the form \(ax^2+bx+c\) where \(a\), \(b\), and \(c\) are constants.

Final Answer :
C
Explanation :
The trinomial can be factored by looking for two numbers that multiply to -36 and add to -5. Those numbers are -9 and +4. Therefore, the factored form is (xn−9)(xn+4)(x^n - 9)(x^n + 4)(xn−9)(xn+4) .
