-3(8n - 5) - 2n = 8n - 21

BigorU [14]

Answer:

Step-by-step explanation:

First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15

so it will look like this. -24n+15-2n=8n-21

Now combine like terms the -24n-2n.

-26n+15=8n-21 now subtract 8n now it will look like this

-34n+15=-21 now -15 from -21

-34n=-36

now if you want n by its self divide -34 and -36

Divide x ^ 4 + x - 1 by x - 1

vladimir2022 [97]

The required, divide is given by $=x^3+x^2+x+2+\frac{1}{x-1}$

<h3>What is fraction of polynomial?</h3>

Fraction of polynomial is, in the numerator and in the denominator of a fraction there is polynomial function

$=x^3+\frac{x^3+x-1}{x-1}\\$

$=x^3+x^2+\frac{x^2+x-1}{x-1}\\$

$=x^3+x^2+x+\frac{2x-1}{x-1}\\$

$=x^3+x^2+x+2+\frac{1}{x-1}$

Thus the required, divide is $=x^3+x^2+x+2+\frac{1}{x-1}$ .

Can I see how long division works on these? pls no sketchy links

alexandr1967 [171]

Answer:

Step-by-step explanation:

11) First write in decreasing exponential terms and fill in blanks with zeros.

Our goal is to eliminate all term in the dividend by subtraction

________________

2v - 2 | 2v³ - 16v² + 0v + 13

we see that 2v needs to be multiplied by 1v² to eliminate the first term

<u> v² </u>

2v - 2 | 2v³ - 16v² + 0v + 13

<u>- (2v³ - 2v²)</u>

0 - 14v²

multiply your estimate by your divisor and subtract from the dividend.

bring down the next term and repeat.

<u> v² -7v </u>

2v - 2 | 2v³ - 16v² + 0v + 13

<u>- (2v³ - 2v²)</u>

0 - 14v² + 0v

<u>-(-14v² + 14v)</u>

- 14v

repeat again

<u />

<u> v² - 7v - 7 </u>

2v - 2 | 2v³ - 16v² + 0v + 13

<u>- (2v³ - 2v²)</u>

0 - 14v² + 0v

<u>-(-14v² + 14v)</u>

- 14v + 13

<u>-(-14v + 14)</u>

-1

and remainder gets put over the divisor and appended

v² - 7v - 7 - 1/(2v - 2)

13) Same process

<u> </u>

5a + 1 | 40a³ - 12a² - 39a - 5

<u> 8a² </u>

5a + 1 | 40a³ - 12a² - 39a - 5

<u>-(40a³ + 8a²)</u>

-20a² - 39a

<u> 8a² - 4a </u>

5a + 1 | 40a³ - 12a² - 39a - 5

<u>-(40a³ + 8a²)</u>

-20a² - 39a

-(-<u>20a² - 4a)</u>

-35a - 5

<u> 8a² - 4a - 7 </u>

5a + 1 | 40a³ - 12a² - 39a - 5

<u>-(40a³ + 8a²)</u>

-20a² - 39a

-(<u>20a² - 4a)</u>

-35a - 5

-<u>(-35a - 7)</u>
