Divide by using long division

(8x^3 + 6x^2 + 7) ÷ (x + 2)

3.4    Polynomial Long Division

Dividing :  8x3-6x2-23x+6  

                             ("Dividend")

By         :    x-2    ("Divisor")

dividend     8x3  -  6x2  -  23x  +  6  

- divisor  * 8x2     8x3  -  16x2          

remainder         10x2  -  23x  +  6  

- divisor  * 10x1         10x2  -  20x      

remainder          -  3x  +  6  

- divisor  * -3x0          -  3x  +  6  

remainder                0

Quotient :  8x2+10x-3  Remainder:  0

Step-by-step explanation:

i have no idea but this is what i found.

right

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
