Question

subtract.
(6m + 8) - (2m + 4)

Explanation:

Step1: Remove parentheses

To subtract the two polynomials, we first remove the parentheses. When we have a minus sign in front of a parentheses, we distribute the negative sign to each term inside the parentheses. So, \((6m + 8)-(2m + 4)=6m + 8-2m - 4\).

Step2: Combine like terms

Next, we combine the like terms. The like terms for the \(m\) terms are \(6m\) and \(-2m\), and the constant terms are \(8\) and \(-4\). Combining the \(m\) terms: \(6m-2m = 4m\). Combining the constant terms: \(8 - 4=4\). So, putting it together, we get \(4m + 4\).

Answer:

\(4m + 4\)
