Ella completed the division problem below. 1.848 divided by 0.6. 6 StartLongDivisionSymbol 184.8 EndLongDivisionSymbol minus 18 = 48. 48 minus 48 = a remainder of 0 and a quotient of 30.8.
What is Ellen’s error?
She included a 0 in the quotient, which does not belong.
She multiplied the dividend by 100 instead of 10.
She should have multiplied both numbers by 100.
She did not subtract correctly in one of the steps.

(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
