Answer:
Step-by-step explanation:
Sum of exterior angles of regular polygons is 360°.
If each angle measures 15°, then the number of sides:
- 15n = 360
- n = 360/15
- n = 24
Answer:
The factor form is:

Step-by-step explanation:
Here we have to find the factor of the expression:

So we need to take out the common terms, as we do for finding the greatest common factors.
Now the expression that is given can be re-written as:

Next, we will find the common terms, as follows;

Now we will factorise the expression:

as follows;

So the final factor form is:
