Now write an equivalent expression with the fewest possible terms.
(24c+3d)−(6c+15d)
= 24c + 3d + −6c + −15d
= 24c + −6c + 3d + −15d

Great job!
Factor to rewrite the expression another way. To start factoring, choose the greatest common factor of 18c and −12d.
(24c+3d)−(6c+15d)
= 24c + 3d + −6c + −15d
= 24c + −6c + 3d + −15d
= 18c+−12d

You got it!
Now find the factors that, when multiplied by 6, equal 18c and −12d and fill them in the parentheses to write the factored expression.
(24c+3d)−(6c+15d)
= 24c + 3d + −6c + −15d
= 24c + −6c + 3d + −15d
= 18c+−12d

Answer 1

Let's go through the steps as outlined and fill in the blanks.

1. Starting with the expression \((24c + 3d) - (6c + 15d)\):

First, we distribute the negative sign:

\[
= 24c + 3d - 6c - 15d
\]

2. Next, we group like terms together:

\[
= (24c - 6c) + (3d - 15d)
\]

3. Simplifying the grouped terms gives:

\[
= 18c - 12d
\]

4. To factor out the greatest common factor (GCF) from \(18c\) and \(-12d\), we find that the GCF is \(6\).

Therefore:

\[
= 6(3c - 2d)
\]

In summary, we can rewrite the original expression as follows:

\[
(24c + 3d) - (6c + 15d) = 6(3c - 2d)
\]

So the filled-in expression is:

\[
6(3c + (-2d))
\]

Thus, the complete factored form is:

\[
(24c + 3d) - (6c + 15d) = 6(3c - 2d)
\]
