Find the product. -2xa(-4xb - 2x 3 + 5x)

A) 8 xa+b + 4 x3a - 10 xa
B) 8 xa+b + 4 xa+3 - 10 xa+1
C) -8 xa+b - 4 xa+3 - 10 xa+1

b

Step-by-step explanation:

-2xa ×-4xb=8xa+b

-2xa×-2x3=4xa+3

-2xa×5x=10xa+1

(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
