Complete the synthetic division problem below. What is the quotient in polynomial form?
stellarik [79]
The polynomial would be 2x+5.

We bring down the first number inside the box, 2, unchanged.

    _______
-1|  2   7   5
    _______
      2

Now we multiply that 2 by the number outside, -1:
    _______
-1|  2   7   5
    <u>      -2     
</u>      2

Now we add the two numbers in the middle column:
    ________
-1|   2   7   5
    <u>       -2      </u> 
       2   5

Multiply the 5 we brought down by the -1:
    ________
-1|   2   7   5
    <u>       -2  -5 
</u>       2   5   

Add the numbers in the last column:
    ________
 -1|   2   7   5
     <u>       -2  -5
</u>        2   5   0

The 3 numbers under the box represent the coefficients of x² and x, as well as the constant.  When we finish, we no longer have an x², but start at the next level down, which would be x.  2 would be the coefficient of x and 5 would be the constant, with 0 remainder.

Find the consecutive odd integers that have a sum of 9. order them from least to greatest
ikadub [295]

Hello from MrBillDoesMath!

Answer:

No solution is possible using odd consecutive integer

Discussion:

Let "n" be the smaller odd integer. Then

n + (n+2) = 9 =>

2n + 2 = 9 =>

2n = 7 =>    Oops!  2n is an even integer; 7 is odd. NO integer solution exists


Regards,  

MrB

 

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
