Let's start with the given polynomial:
2x² - 12xy - 32y²
As a first step, we want to regroup 2:
= 2(<span>x² - 6xy - 16y²)
Now, we want to re-write the term -6xy in order to be able to perform a partial factoring. In this case, we can write:
-6xy = -8xy + 2xy
Therefore, the polynomial becomes:
= </span>2(<span>x² - 8xy + 2xy - 16y²)
Now we factorize x within the first two terms and 2y within the last two:
</span>= 2[x(x - 8y) + 2y(x - 8y)]
We can now regroup the common term:
=2(x - 8y)(x + 2y)
Your answer is hence B = 2
Answer:
when f(x) is -1, f(x) = -3
when f(x) is 0, f(x) = 1
when f(x) is 3, f(x)= 13
so is -3, 1 and 13.
you basically replace x with the number and then evaluate

Answer:
12k^5 +24k⁴+30k³
Step-by-step explanation:
the area = 6k³(2k²+4k+5)
= 12k^5 +24k⁴+30k³
8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
