Don't really know how to explain it, but here's an example on how to factor out the coefficient of the variable, hope this explains it!
Factoring out the coeffecient of a variable:
Example:
9x-36
How to factor the coeffecient of the variable: Would then get 9(x-36)
Another example:
1/5k+15
Answer: (1/5)(k+15)
Clear out any fractions by Multiplying every term by the bottom parts.
Add or Subtract the same value from both sides.
Divide every term by the same nonzero value.
Combine Like Terms.
Factoring.
Expanding (the opposite of factoring) may also help.

Step-by-step explanation:
It is in the form of a² - b²
so it's correct product is
64x² - 16
Answer:y=-3
Step-by-step explanation:yes firs multiply everything by -3 in parenthesies
Then you would subtract 15 from both sides
Next you would divide 9 by -3 and you would get -3
So y =-3
