Use synthetic division to divide (x3 + x2 – 40x – 4) ÷ (x – 6).

a. x2 + 7x + 2 r 8
b. x2 + 5x – 2 r 6
c. x3 + 6x – 1 r 2
d. x2 – 7x + 3 r 5
for

The quotient and remainder (R) is 8

A is correct

Step-by-step explanation:

Given: Synthetic division

Synthetic division: First we write coefficient of polynomial of numerator and then divide by bottom number when 0

Set of synthetic division:

 6  |  1       1      -40     -4  |

                6       42     12

        1       7        2       8

First we put 1 down and then  multiply it by 6. Write the result below next number. Repeat the step till end.

At last we get number 8. This is remainder.

Rest are coefficient of quotient.

Please find the attachment for steps of synthetic division.

Hence, The quotient and remainder (R) is 8

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )
