What is the working for 6 3/4 x 5 2/3

Step-by-step explanation:

One of the easier ways in which to complete this multiplication is to convert the multiplicands 6 3/4 and 5 2/3 into improper fractions:

6 3/4 = 27/4

5 2/3 = 17/3

Then we multiply:

27/4 *17/3

This reduces to 9(17)/4, or 153/4, or 38 24, or 30 7/20.  All of these rsults are correct.

(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
