Answer:

A

Step-by-step explanation:

Check the solution by substituting x = \frac{\pi }{2} into the left side of the equation

2sin²x - sinx - 1

= 2sin²(\frac{\pi }{2} ) - sin (\frac{\pi }{2} ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

= right side

\frac{\pi }{2} is therefore a solution to the equation
