Answer:
Step-by-step explanation:
Associative property
For this case we have the following polynomial:

We make the following change of variables:

Rewriting we have

Factoring the second order polynomial we have:

Then, returning the change we have:

Finally, we factor the expression in the parentheses of the second term:

Answer:
the completely factored form is:

Your answer would be -1/6
I have more problems then this.
The minimum degrees to map onto itself is 360/5 = 45 degrees.
It will take 2 increments for A' to coincide with C.
