Here is the solution process:

                    <u>  </u><u>3 x² -  2 x  -   6    </u><u>                  </u>

x² + 0x + 2 | 3 x⁴ -  2 x³ +  0  x² -     x -   4

                    <u>3  x⁴ + 0 x³ +  6  x²                 </u>

                             - 2 x³  -  6  x² -      x -   4

                             <u>- 2 x³  + 0  x² -   4 x        </u>

                                        -  6  x² +  3 x  -  4

                                        <u>-  6  x²  + 0 x  -  12</u>

                                                        3 x  + 8

Long division:

  • Standard: \sf{3x^{2} -2x-6+\dfrac{3x+8}{x^{2} +2} \ \ \to \ \ \ Option \ "A" }
  • Quotient: 3x² - 2x - 6
  • Rest: 8 + 3x

Therefore, the correct option is "A".

Check the picture below.

notice, the dividend and divisor must be in descending order, and when one of the variables is "missing", is really not missing, it simply has a coefficient of 0.

a recipe calls for three cups of cheese to make nachos for six people .how much cheese is needed to make nachos for two dozen pe
zubka84 [21]
First, let's figure out how many cups of cheese we need for one dozen people. 
There are 12 people in one dozen. 

<u>3 cups of cheese </u> = <u>x cups of cheese</u>
    6 people                     12 people
<u>
</u>
that means we will need 6 cups of cheese for 12 people, or one dozen. 

However, we want to make nachos for two dozen people. 

6 cups of cheese for one dozen x 2 dozen = 12 cups of cheese

<em>You need 12 cups of cheese to make nachos for two dozen people. </em>
