So firstly, we have to factor out the GCF, or greatest common factor, of these terms. To find the GCF, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 3x:
Next, what's inside the parentheses is considered a perfect square. Using this format of , we can factor it as such:
<u>The factors of this expression are 3x, x + 3, and x + 3.</u>
Answer:
Addition property of equality
Step-by-step explanation:
Given:
We need to find the missing reason in the proof.
Solution:
By solving the above equation we get;
⇒ Given:
Now by adding both side by 'x' we get;
⇒ Addition property of equality
Hence The missing reason in the proof was Addition Property of equality.
