rewrite each of the following expressions without using absolute value.

Question

|2b| if b < 0

Answer 1

If \( b < 0 \), the expression \( |2b| \) can be rewritten without absolute value as:

\[ |2b| = -2b \]

This is because when \( b < 0 \), \( 2b \) will also be negative, and the absolute value function converts it to a positive value by negating it.
