Answer:

  • See below

Step-by-step explanation:

#1 Synthetic method

  • 2x³ + x² - 2x - 4 ÷ x + 1 = 2x² - x - 1 rem 3

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

x + 1 | 2x³ + x² - 2x + 4

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

    -1 |  2       1    -2    4

       <u>|         - 2     1     1 </u>

          2     - 1    - 1    3

#2 Long division

  • 3x³ - 5x² - 26x - 8 ÷ 3x + 1 = x² - 2x - 8

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

3x³ - 5x² - 26x - 8  <u>| 3x + 1</u>     = x² - 2x - 8

<u>3x³ + x²</u>

       -6x² - 26x

       <u>-6x² - 2x</u>

                  - 24x - 8

                  <u>- 24x - 8</u>

                             0

Find two integers whose sum is -3 and product is -18
Mariulka [41]

let two integers be x and y

A.T.Q

x+y= -3

or, x= -3-y(i)

and xy= -18

or,(-3-y)y= -18[by(i)]

or,- -3y-y²= -18

or,-y²= -18+3

or, -y²= -15

or, y²=15

therefore y=✓15

from (i)

x= -3-✓15

y=√15
