Which shows the list below in order from greatest to least. 3.4848, -3 19/20, √11, -3.58, 362%

Free_Kalibri [48]

Let’s go left to right and convert everything to decimals.

3.4848 is 3.4848
-3 19/20 is -3.95
-3.58 is -3.58
Sqrt (11) is about 3.3
362% is 3.62

Using this, you can easily put them in order

What are the zeros of the function f(x) = x^4 - x² - 2?

vaieri [72.5K]

Answer:

$x= i\\\\ x = -i \\\\x=\sqrt 2\\\\x = -\sqrt 2$

Step-by-step explanation:

$~~~~~~x^4 -x^2 -2=0\\\\\implies x^2 \cdot x^2-2x^2 +x^2 -2 = 0\\\\\implies x^2(x^2 -2) +(x^2 -2) =0\\\\\implies (x^2 +1)(x^2 -2) = 0\\\\ \implies x^2 +1=0~~~~~~~~\text{or}~~~~~~~~~x^2 -2 = 0\\\\ \implies x = \pm\sqrt{-1}~~~~~~~\text{or}~~~~~~~~~~ x = \pm\sqrt 2\\\\\implies x= \pm i~~~~~~~~~~~~~\text{or}~~~~~~~~~ x= \pm\sqrt 2$
