Question 844746: A polynomial P is given.
P(x) = x^5 − 81x
(a) Factor P into linear and irreducible quadratic factors with real coefficients.
I typed in P(x) = x(x^4-81) and received the message below.
Incorrect: Your answer is incorrect.
(b) Factor P completely into linear factors with complex coefficients.
P(x) =
