Find a polynomial with the following zeros. HELPPPP ASAPPP

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
8 0

<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>

Can anybody help me out?
charle [14.2K]

You need to isolate the "x" in both inequalities

5x + 7 ≤ -3     Subtract 7 on both sides

5x ≤ -10    Divide 5 on both sides

x ≤ -2


3x - 4 ≥ 11     Add 4 on both sides

3x ≥ 15  Divide 3 on both sides

x ≥ 5


This is your simplified inequalities:

5x + 7 ≤ -3 or 3x - 4 ≥ 11   --------->     x ≤ -2 or x ≥ 5      Your answer is A
