Answer:

A. x = {nπ, π/4 +nπ}

Explanation:

The zero product rule tells you the solutions are found where the factors are zero:

tan(x) = 0 ⇒ x = nπ

tan(x) -1 = 0 ⇒ x = arctan(1) +nπ = π/4 +nπ

_____

When working with functions of trig functions, it is helpful to have an idea of the general shape of their graphs and a few "special" values.
