11. factor the expression. k2 – 16h2 (k 4h)(k – 4h) (k – 4h2)(k 4) h2(k 4)(k – 4) (k 4h)(k 4h)

The correct option is 1.

Step-by-step explanation:

The given expression is

It can be rewritten as

              .... (1)

The formula for difference of squares:

In equation (1), a=h and b=4h. Using the above formula we get

The factor form of given expression is (k-4h)(k+4h). Therefore the correct option is 1.
