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

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

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:

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