Factoring polynomial expressions(quadratic) x^2-6x+5

Mathematics
1 answer:
weeeeeb [17]3 years ago

Answer:

x = 5 and x = 1 are the factors

Step-by-step explanation:

<h2>step 1) </h2>

identify the a, b, and c values (a=1 b= -6 c=5)

<h2>step 2) </h2>

plug them into the quadratic formula

x = -(-6) ± √(-6)² - 4(1)(5) / 2(1)

<h2>step 3) </h2>

multiply -1 by -6 to get 6

x = 6 ± √(-6)² - 4(1)(5) / 2(1)

<h2>step 4)</h2>

multiply -6 by -6 to get 36

x = 6 ± √36 - 4(1)(5) / 2(1)

<h2>step 5)</h2>

multiply 4 by 1 to get 4

x = 6 ± √36 - 4(5) / 2(1)

<h2>step 6) </h2>

multiply 4 by 5 to get 20

x = 6 ± √36 - 20 / 2(1)

<h2>step 7)</h2>

subtract 36 by 20 to get 16

x = 6 ± √16 / 2(1)

<h2>step 8) </h2>

take the square root of 16 to get 4

x = 6 ± 4 / 2(1)

<h2>step 9)</h2>

multiply 2 by 1 to get 2

x = 6 ± 4 / 2

<h2>step 10) </h2>

add 6 by 4 to get 10

x = 10 / 2

<h2>step 11) </h2>

divide 10 by 2 to get 5 (now you know the first factor is x=5)

x = 5

<h2>step 12)</h2>

subtract 6 by 4 to get 2

x = 2 / 2

<h2>step 13)</h2>

divide 2 by 2 to get 1 (now you have found the final factor x=1)

<h2>step 14)</h2>

you know know that the factors of x²- 6x + 5 are<em><u> x = 5 and x = 1</u></em>

For her 1st birthday, Ruth's grandparents invested $1000 in an 18-year certificate for her that pays 10% compounded annually. Ho
Lyrx [107]

Answer:

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Step-by-step explanation:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

P = 1000, n = 1, r = 0.1, t = 18

So

A = 1000(1 + \frac{0.1}{1})^{1*18}

A = 5559.92

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Taxi B
1mile £1.25+£2.00=£3.25

Taxi A
2miles £3.50+£3.50=£7.00
Taxi B
2miles £1.25+£4.00=£5.25

Taxi A
3miles £3.50+£5.25=£8.75
Taxi B
3miles £1.25+£6.00=£7.25

Taxi A
4miles £3.50+£7.00=£10.50
Taxi B
4miles £1.25+£8.00=£9.25

Taxi A
5miles £3.50+£8.75=£12.25
Taxi B
5miles £1.25+£10.00=£11.25

Taxi A
6miles £3.50+£10.50=£14.00
Taxi B
6miles £1.25+£12.00=£13.25

Taxi A
7miles £3.50+£12.25=£15.75
Taxi B
7miles £1.25+£14.00=£15.25

Taxi A
8miles £3.50+£14.00=£17.50
Taxi B
8miles £1.25+£16.00=£17.25

Taxi A
9miles £3.50+£15.75=£19.25 (the same)
Taxi B
9miles £1.25+£18.00=£19.25 (the same)

^^^
They would have to drive 9 miles for the taxi to cost the same.

Hope this helped, this is the longest way to work it out but also the simplest.
