Which procedure justifies whether -3X(6-4)+3(x-6) is equivalent to -12x-6?
The expressions are not equivalent because -3(2)(5-4)+3(2-6) = -18 and -12(2)-6--30
The expressions are not equivalent because 3(2)(6-4)+ 3(2-6)= -18 and -1203)-5--42
O
The expressions are equivalent because -3(2)(5-4)+ 3(2-6)= -18 and -12(-2)-6-18
The expressions are equivalent because -3(2)(5-4)+ 3(2-6) = -18 and -12(1)-6=-18

The answer is 12a3 + 2a + 23a + 18

Step-by-step explanation:

for the points

step-by-step explanation:

(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
