Answer:
Yes.
Step-by-step explanation:
Given: f(x) = 2x^3 + x^2 - 5x + 2; x + 2
If x + 2 is a factor of f(x), then , by the Factor Theorem, f(-2) = 0.
So we check if this is so:
f(-2) = 2(-2)^3 + (-2)^2 - 5(-2) + 2
= -16 + 4 + 10 + 2
= -16 + 16 = 0.
So Yes x + 2 is a factor.
Given :
We know the identity
We use this property to simplify the left hand side
So 
we know ,
when 
then
For
Add 
on both sides
Finally we add 2npi for general solution
So options C and D are correct
Answer:
therefore According to the diagram y= start over
The solution is where the lines cross. So your x coordinate is 3.Click to let others know, how helpful is it
