What is the complete factorization of the polynomial function over the set of complex numbers?

f(x)=x3−5x2+4x−20

Enter your answer in the box.

Answers

Answer:

[tex]x^3-5x^2+4x-20=(x-5)(x+2\mathbf{i})(x-2\mathbf{i})[/tex]

Step-by-step explanation:

Factorization of polynomials

Factor:

[tex]f(x)=x^3-5x^2+4x-20[/tex]

There are several techniques to factor polynomials. We'll use algebraic manipulation and common factor:

Separate in groups:

[tex](x^3-5x^2)+(4x-20)[/tex]

Factor out 4 from 4x-20:

[tex]=(x^3-5x^2)+4(x-5)[/tex]

Factor out [tex]x^2[/tex] from [tex]x^3-5x^2[/tex]

[tex]=x^2(x-5)+4(x-5)[/tex]

Factor out x-5:

[tex]=(x-5)(x^2+4)[/tex]

The roots of

[tex]x^2+4=0[/tex]

Are two complex numbers:

[tex]x=2\mathbf{i}, x=-2\mathbf{i}[/tex]

The complete factorization is:

[tex]\boxed{x^3-5x^2+4x-20=(x-5)(x+2\mathbf{i})(x-2\mathbf{i})}[/tex]

Step-by-step explanation:

The winner of an election received 1 more than 3 times as many votes as his opponent received. Let w represent the number of votes the winner received. Let x represent the number of votes his opponent received. Which question could be used to find the number of votes the winner received if the number of votes his opponent received is known?

Answers

Answer:

w=3x+3

Step-by-step explanation:

Given that the winners vote is represented by w

and that the opponents vote is represented by x

the question states that "The winner of an election received 1 more than 3 times as many votes as his opponent received"

Translated to mathematical expression we have

w=3(x+1)

w=3x+3

therefore the equation to find the number of votes his opponent received is known is

w=3x+3

A mercury thermometer records a temperature of 8 degrees Fahrenheit at 10:00am.If the Temperature drops by 3 degrees Fahrenheit every hour,what will be the Temperature by 2:00pm of the same day

Answers

Given:

Temperature at 10:00 am = 8 degrees Fahrenheit

Temperature drops by 3 degrees Fahrenheit every hour.

To find:

The temperature by 2:00pm of the same day.

Solution:

Let y be the temperature after x hour after 10:00 am.

The temperature at 10:00 am is the initial temperature.

So, y-intercept of the linear function is 8.

Temperature drops by 3 degrees Fahrenheit every hour.

So, slope of linear function is -3. Here, negative sign represents the decrease in the temperature.

Slope intercept form of a linear function is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Substitute m=-3 and y=8 in the above equation.

[tex]y=-3x+8[/tex]

Difference between 2:00pm and 10:00 am is 4 hours. So, substitute x=4 in the above equation.

[tex]y=-3(4)+8[/tex]

[tex]y=-12+8[/tex]

[tex]y=-4[/tex]

Therefore, the temperature by 2:00pm of the same day is -4 degrees Fahrenheit.

A fraction is written in the form of a numerator and a denominator.There are two types of fractions. One is proper fraction in which numerator is less than the denominator and another one is improper fraction in which denominator is less than the numerator.All fractions can be written in the form of p/q, where q ≠ 0 cause anything divided by 0 is undefined.
