To determine the variables present in the expression \( 4x + 2y - 82b \), we need to identify the different variables used in that expression:
- \( x \)
- \( y \)
- \( b \)
There are three distinct variables: \( x \), \( y \), and \( b \).
When dividing this polynomial by any expression, the number of variables that will appear in the quotient depends on the specific divisor used. However, since the original expression contains three variables, the quotient can potentially still have up to three variables, depending on the context.
Thus, the answer to the question of how many variables will be present in the quotient is 3.
