The polynomial is .

First find the coefficients of the x-terms;

Find two numbers with a product of 1 and 16 is 16 and a sum is – 10.

So, the two coefficients must be –2 and – 8.

  (Rewrite the expression using coefficients)

Apply associative property of addition: a + (b + c) = (a + b) + c.

Find the Greatest Common factor (GCF) of each group.

Greatest Common factor (GCF) of is x.

Greatest Common factor (GCF) of is – 8.

                   (Factor out the GCF)

Rewrite the expression using Distributive Property

The polynomial is not a perfect square trinomial.
