What is the missing constant term in the perfect square that starts with x 2 − 16 x x 2 −16xx, squared, minus, 16, x ?

64

Step-by-step explanation:

Given:

The perfect square, that starts with: x² -16x

We need to find the missing constant term

Let the missing term be k

Since x² - 16x + k is perfect square, it can be shown as:

Comparing this with the original polynomial, we see that:

Then:

The missing term is 64 and the perfect square is:
