Got stuck on finding property “a” in said polynomial

Hence, in the simplification of the value of a  = 9.

Step-by-step explanation:

Here, the given expression is

Simplify this given expression, we get:

Now, the given expanded form is

Comparing it with given second last step in simplification, we get

Comparing all term on both sides, we get

ay =  9y

and -ay =  -9y

⇒ a = 9 on both sides.

Hence, in the simplification of the polynomial, the value of a  = 9.

dont think so
