If f(x)=2x^3-6x^2-16x-20f(x)=2x *3 −6x *2−16x−20 and f(5)=0, then find all of the zeros of f(x)f(x) algebraically.

mihalych1998 [28]

The zeros of the cubic function f(x) = 2x³ - 6x² - 16x - 20 are given as follows:

x = 5, x = -1 + i, x = -1 - i.

<h3>How to obtain the solutions to the equation?</h3>

The equation is defined by the rule presented as follows:

f(x) = 2x³ - 6x² - 16x - 20.

One solution for the equation is given as follows:

x = 5.

Because f(5) = 0.

Then (x - 5) is a linear factor of the function f(x), which can be written as follows:

2x³ - 6x² - 16x - 20 = (ax² + bx + c)(x - 5).

This is because the product of a linear function and a quadratic function results in a cubic function.

Now we expand the right side to begin finding the coefficients of the quadratic function that we are going to solve to find the remaining zeros:

2x³ - 6x² - 16x - 20 = = ax³ + (b - 5a)x² + (c - 5b)x - 5c.

Then these coefficients are obtained comparing the left and the right side of the equality as follows:

a = 2.

-5c = -20 -> c = 4.

b = -6 + 5a = 4.

Hence the equation is:

2x² + 4x + 4.

Using a quadratic equation calculator, the remaining zeros are given as follows:

x = -1 + i.

x = -1 - i.

Answer:

x = 3

Step-by-step explanation:

Perform the indicated multiplication, using the distribution rule:

10 + 6x = 4x + 16

Gathering the first powers of x on the left and the constants on the right, we get:

2x = 6, or x = 3

You are baking chocolate chip cookies. One batch makes 4 dozen big cookies. The recipe calls for 3/4 cup brown sugar. How many c

Over [174]

Greetings!

11/4=2.75
To make 11 dozen cookies, you would need to make 2.75 times the recipe.
Therefore, you will need 2.75 times the brown sugar:

$3/4*2.75$
$=3/4*2 \frac{3}{4}$
Convert the mixed fraction into an improper fraction.
$=3/4*11/4$
$=33/16$
Convert back into a mixed fraction.
$=2\frac{1}{16}$

You would need 2 1/6 cups of brown sugar to make 11 dozen cookies.

Hope this helps.
