Heather bought 3 bags of candy. Each bag was originally priced at $5.00 each, but were on sale for $2.00 off the original price. She gave the cashier a twenty-dollar bill. Which equation represents the amount of change she should recieve? A. 20-3x5-2=c C. 20-3(5-2)=c
B. (20-3)(5-2)=c D. 20+3(5-2)=c

(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
