Step-by-step explanation:
First of all let's notice that while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of
it means tha
is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)
At this point 2 is a zero, and our final factoring is a

The diagram for this problem is shown below. Point E is the intersection of the two diagonals and we know that:
Every internal angle of any rectangle measures 90 degrees, so:
So:
So the measure of angle BEC can be found as follows:
We know that triangle ΔCEB is an isosceles triangle because the diagonals of any rectangle measure the same. So
The sum of internal angles of any triangle add up to 180 degrees, so:
