What are the factors of the following quadratic equation 12=x^2-x

1 answer:

8 0

12 = x² - x
12 - 12 = x² - x - 12
0 = x² - x - 12
x² - x - 12 = 0
x = <u>-(-1) +/- √((-1)² - 4(1)(-12))</u>
   2(1)
x = <u>1 +/- √(1 + 48)</u>
   2
x = <u>1 +/- √(49)
</u> 2
x = <u>1 +/- 7</u>
   2
x = 0.5 +/- 3.5
x = 0.5 + 3.5 x = 0.5 - 3.5
x = 4 x = -3

Find an nth degree polynomial function with real coefficients satisfying the given conditions.

damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

$(x - 3)(x - i)$

Since i is one root, it conjugate, must be the other.

so we have

$(x - 3)(x - i)(x + i)$

Simplify

$( {x}^{2} + 1)(x - 3)$

${x}^{3} - 3 {x}^{2} + x - 3$

So the function is

$x {}^{3} - 3 {x}^{2} + x - 3$

8% of the employees at a shop work part-time.

nikitadnepr [17]

There are 50 employees in total

<h3>How to determine the total employee?</h3>

The given parameter is:

Part-time = 8% of total employee

Rewrite as:

Part-time = 8% * total employee

There are 4 part-time employees.

So, we have:

8% * total employee = 4

Divide both sides by 8%

total employee = 50

Hence, there are 50 employees in total

How many quarts does it take to fill a kitchen sink

Anna [14]

The average kitchen sink has a width of approximately 23.5 inches, a length of approximately 31.5 inches, and a depth of approximately 21 inches.

Multiplying these values together, we can see that the volume of the average kitchen sink is about 15545.25 cubic inches.

The conversion of cubic inches to liquid gallons is 1 cubic inch = approximately 0.004329 gallons.

Multiplying these numbers, we can see that 15545.25 cubic inches is the same as approximately 67.29538725 gallons. Now, we just have to multiply that number by 4, since there are 4 quarts in a gallon.

67.29538725 * 4 = 269.181549

It takes approximately 269.181549 quarts to fill the average kitchen sink.
Hope that helped =)
