Nuetrik [128]

The remaining values will be<u> 19, 20, 21, 22 and 23</u>

<h3 /><h3>System of equations</h3>

Given the following parameters

Ethan's score = x points

His younger sister's score = 8 points

If their total score is y points, hence the  equation relating x and y is expressed as:

x + 8 = y

x = 8 - y

If x = 10

y = x + 8

y = 18

The ramining values will be<u> 19, 20, 21, 22 and 23</u>

Find a polynomial with the following zeros. <br><br> HELPPPP ASAPPP
Pavlova-9 [17]

<u>Answer:</u>

x³ - 4x² + 2x + 4 = 0

<u>Here's how I solved this:</u>

<u>You start off by rewriting the zeros into factors:</u>

1 - √3    →    x = 1 - √3    →    (x - 1 - √3)

  2        →    x = 2           →    (x - 2)

1 + √3   →    x = 1 + √3   →    (x - 1 + √3)

<u>Now you want to multiply the factors together:</u>

     (x - 1 - √3) · (x - 2) · (x - 1 + √3)

<em>- Multiply the first two factors together -</em>

                (x - 1 - √3) · (x - 2)

                              ↓

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

 

<em>    - Combine like terms and simplify -</em>

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

                              ↓

          (x² - 3x - √3 · x + 2√3 + 2)

<em>       - Now multiply the third factor -</em>

   (x² - 3x - √3 · x + 2√3 + 2)(x - 1 + √3)

                              ↓

(x² · x + x² · √3 - x² - 3x · x - 3x · √3 + 3x - √3 · xx - √3 · x · √3 +√3 · x + 2 · √3 · x + 2 · √3 · √3 - 2 · √3 + 2x + 2 · √3 - 2)

                              ↓

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

<em>    - Combine like terms and simplify -</em>

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

                              ↓

                 x³ - 4x² + 2x + 4

--------------------------------------------------------------------------------------------------------------

And there we get our solution: <u>x³ - 4x² + 2x + 4</u>
