Josh is trying to factor the expression - 20a - 8 - 12b. He writes - 4 (5a + 2 + 3b). What error did Josh likely make?

The error make by Josh is none.

Step-by-step explanation:

Given as:

The actual expression is written as ( - 20 a - 8 - 12 b)

The expression written by Josh as - 4 (5 a + 2 + 3 b)

Now, From the actual expression, if we take the common term

Then - 4 (5 a + 2 + 3 b)

The actual expression after taking common term 4, is written as

- 4 (5 a + 2 + 3 b)

And The expression written by Josh is also - 4 (5 a + 2 + 3 b), which is the similar one.

So, no error makes by Josh

Hence The error make by Josh is none. Answer
