Question

Find the missing term that completes the square of a² + 4a

Answer 1

4

Step-by-step explanation:

Given the expression:

`a^2+4a`

To complete the square:

First, identify the coefficient of a.

• The coefficient of a = 4

Next, divide the coefficient by 2 and square it.

`\begin{gathered} (4)/(2)=2 \\ 2^2=4 \end{gathered}`

Thus, the missing term that completes the square of a² + 4a​ is 4.
