Discuss the validity of the statement below. If the statement is true, explain why. If not, give a counterexample. If n is a positive integer greater than 1, then un + vn can be factored. Choose the correct answer below. A. The statement is true because un + vn is a perfect square, which can be factored. B. The statement is true. For any n, where n is a positive integer greater than 1, un +vn is factorable because u = - v is a solution to the equation un + v₁ = 0. Therefore, un + vn always has u + v as a factor. C. The statement is false. When n = 2, un + vn is of the form u² + v². This is a known form that is not factorable since u² + v² ± (au + bv)(cu + dv) for any choice of real number coefficients a, b, c, and d. D. The statement is false. When n = -2, un + vn can still be factored. In fact, -2 u2+v² = (u-v)(u + v).

Question

B is not correct 

Discuss the validity of the statement below. If the statement is true, explain why. If not,
give a counterexample.
If n is a positive integer greater than 1, then un + vn can be factored.
Choose the correct answer below.
A. The statement is true because un + vn is a perfect square, which can be
factored.
B. The statement is true. For any n, where n is a positive integer greater than 1,
un +vn is factorable because u = - v is a solution to the equation un + v₁ = 0.
Therefore, un + vn always has u + v as a factor.
C. The statement is false. When n = 2, un + vn is of the form u² + v². This is a
known form that is not factorable since u² + v² ± (au + bv)(cu + dv) for any
choice of real number coefficients a, b, c, and d.
D. The statement is false. When n = -2, un + vn can still be factored. In fact,
-2
u2+v² = (u-v)(u + v).
