Given:

The given equation is

x^2-8x+16=0

To find:

The correct statement for the given equation.

Solution:

We have,

x^2-8x+16=0

It can be written as

x^2-2(x)(4)+(4)^2=0

Using the identity of perfect square trinomial, we get

(x-4)^2=0 $[\because (a-b)^2=a^2-2ab+b^2]$

(x-4)=0

x=4

Here, x=4 has multiplicity two because the power of factor (x-4) is 2.

x=4 is a double root and the equation is a perfect trinomial.

Therefore, the correct options are C and E.
