1 (4 x 12) + (4 x 8) 2 4 x (12 - 8) 3 (4 x 12) - ( 4 x 8) 4 4 x (12 + 8) Which expression shows 4 times the difference between 12 and 8.

4 x (12 - 8)

Step-by-step explanation:

the word difference really means exactly what it is saying. it is the quantity difference between two numbers. like, if someone would say, "what's the difference between 4 and 2?' then you would just subtract 2 from 4 to find the difference between the two numbers.

so, we now know that we are going to be subtracting 8 from 12.

plus, it tells us to show 4 times 12 - 8. that means that we will be multiplying (12 - 8) by 4.

so, our only viable option is 4 x (12 - 8).

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
