( x^4 - 4 x³ + 2 x² - 4 x + 1 ) : ( x² + 1 ) = x² - 4 x + 1
- x^4 - x²
------------------------
- 4 x³ + x² - 4 x
4 x³ + 4 x
-----------------------
x² + 1
- x² - 1
----------------
R ( x ) = 0
( x^4 - 4 x³ + 2 x² - 4 x + 1) = ( x² + 1 ) ( x² - 4 x + 1 )
<u>Step-by-step explanation:</u>
The vertex form of an absolute value equation is: where
(h, k) is the vertex. In the given equation, , the h-value is 1/2 and the k-value is -2.
So, the vertex (h, k) = (1/2, -2)
Answer:
6%
Step-by-step explanation:
57 divided by 80 = 0.5875
.5875 rounded to the nearest tenth is 6%
Answer:
4 because 5 times 4 is 20 and 3 times 4 is 12
