1. solve 5x+2y-3z=4
-2x-4y + z= -8
x+y+z=2

answer choices:
a. (2,0,0)
b. (0,2,0)
c. (2,-2,0)
d. (0,-6,9)

Solving equations 5X+2y-3z=4, -2x-4y + z= -8 and X+y+z=2 will give use three answers. The x y and z value. The value for x = 0, for y = 2 and z = 0. The answer is letter B, (0, 2, 0).

(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
