Answer:
We have the function cos(x)*(cos(x) + 1) = 0
Here we have two sides of an equation:
if cos(x) = 0, then the equation is equal to zero (because this therm is multiplicating the whole equation), so the values pi/2, 3pi/2, etc, are solutions.
And if the parentheses is zero, (cos(x) + 1) = 0 then the equation is also zero
Then when cos(x) = - 1 is another solution
This means that x = pi, 3pi, etc.
-45 and +45 since modules are the same thing as absolute value. (I translated the question)
