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)

Rewrite the expression using Associative property

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.
