Respuesta :
Answer: the answers is D. -pi/8 and B. 3pi/8
Step-by-step explanation:
The solution to the equation is B. 3pi/8 and D. -pi/8
What is an Equation ?
A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation in algebra.
One or more variables are used in the most basic and typical algebraic equations.
tan²(2x) - 1 = 0
tan²(2 * pi/2) = 1
tan²(pi) = 0 does not apply
tan²(2 * 3pi/8)= tan²(3pi/4) = 1 applies
tan²(2 * pi/4) = tan²(pi/2) = undefined (does not apply)
tan²(2 *-pi/8) = 1
tan²(-pi/4) = 1 applies
Therefore the answers is B. 3pi/8 and D. -pi/8
