<h2>Steps:</h2>
So for this, I will be factoring by grouping. Firstly, factor x³ + 2x² and -4x - 8 separately. Make sure that they have the same quantity inside of the parentheses:
Now we can rewrite it as:
However, we aren't finished factoring yet. The first factor, x² - 4, can be factored further using the difference of squares. The difference of squares goes by the formula here: . In this case:
<h2>Answer:</h2>
<u>In short, the answer is </u>
Answer:
Mean would increase
Median would stay the same
Step-by-step explanation:
The mean would increase because the lowest number would not make the mean lower
The median would stay the same because there are three numbers with the value of 48, which is the median, and if 45 is gone, it would stay the same
