Final answer:
The expression 27 - 9x + 15y can be factored by identifying the common factor of 3 and then writing the expression as 3(9 - 3x + 5y).
Step-by-step explanation:
To factor the expression 27 - 9x + 15y, we look for common factors in each term. We can see that each term has a factor of 3, so we can factor out the 3 to simplify the expression. The factored form will be 3(9 - 3x + 5y).
Here is how you do it step-by-step:
- Identify the common factor for all terms in the expression, which is 3.
- Divide each term by 3.
- Write down the expression with the common factor pulled out in front.
This results in the factored expression: 3(9 - 3x + 5y).
