Chapter 1.2, Problem 57E

To determine

Tofind:the simplification of the expression.

Answer to Problem 57E

  $m+5$ .

Explanation of Solution

Given:

  $4m+5-3m$ .

Concept used:

Probably the most common thing it will be doing with polynomials is combining like terms.

This is the process of adding together whatever terms it can, but not overdoing it by trying to add together terms that can’t actually be combined and term can combine only if there has the exact same variable portion and exact same variable portion and by exact same.

Calculation:

According to the given:

  $4m+5-3m$ .

Combining the like term as:

  $m+5$ .

If the equation equates to zero then $m=-5$ .

Hence, $m+5$ .
