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:

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

Find the equivalent expression by drawing a line from the left column to the right

Gala2k [10]

Answer/Step-by-step explanation:

$2(3x - 1) = 2*3x 2*-1 = 6x - 2$

$(x*y)2 = (xy)2 = 2xy$

$2(2x - 3) = 2*2x 2*-3 = 4x - 6$

$3x + 4x + 2 = (3x + 4x) + 2 = 7x + 2$

$7x - 7 = 7(x) - 7(1) = 7(x - 1)$

$x(6 + 9) = x(15) = 15x$

$2 + 9x + 1 + 3x = (9x + 3x) + (2 + 1) = 12x + 3$

$4(x + 2) + x = 4x + 8 + x = 4x + x + 8 = 5x + 8$

A grocery store clerk put only cans of tomato soup and cans of chicken soup on a shelf. The ratio of the number of cans of chick

larisa [96]

Answer:

9 cans of tomato soup

Step-by-step explanation:

We are told that only cans of tomato soup and cans of chicken soup are put on the shelf.

Now, we are told that the ratio of the number of cans of chicken noodle soup to the total number of cans on the shelf was 8 to 17.

In fraction, this is 8/17

Now, this implies that there are 8 cans of chicken noodle soup while there are a total of 17 cans on the shelf.

Thus,

Since only cans of chicken noodles and cans of tomato soup are on the shelf, it means;

Cans of tomato soup = 17 - 8 = 9

Factor Completely 5v^2-5v-100

bogdanovich [222]

$5 {v }^{2} - 5v - 100 \\ = 5( {v}^{2} - v - 25) \\ = 5({v}^{2} + 4v - 5v - 20) \\ = 5[v(v + 4) - 5(v + 4)] \\ = 5(v - 5)(v + 4)$
