Answer:
4
Step-by-step explanation:
Answer:

and

respectively.
Step-by-step explanation:
The given trigonometric equation is

We divide both sides by
to get,

This implies that,

We take the inverse tangent of both sides to get,




Since the tangent ratio has a period of
, another solution is

to the nearest degree.
In the third quadrant,




The solutions are

The value of x that satisfies the equation if x lies in the second quadrant is 
The value of x that satisfies the equation if x lies in the third quadrant is

ANSWER
(-1,2)
EXPLANATION
The given quadratic expression is:

The coefficient of the quadratic term is already 1.
So we add and subtract the square of half the coefficient of x.

We factor the first three terms to obtain

This is now in the form:

where (h,k) which is equal to (-1,2) is the vertex.
