20 Identify the value of c that would make this a perfect square trinomial. x^2-16x+underline ( ) square

Question

Answer 1

To make the quadratic expression

a perfect square trinomial, we need to find the value of

that completes the square.A perfect square trinomial takes the form \((x - a)^2 = x^2 - 2ax + a^2\).Comparing this with

, we see that:

Now, we need to find

:

Therefore, the value of

that makes

a perfect square trinomial is:
