Step 1 ⇒ x - 3 = 3(x + 3)
step 2 ⇒ x - 3 = 3x + 9
step 3 ⇒ x = 3x + 12
step 4 ⇒ -2x = 12
step 5 ⇒ x = -6

identify the property of equality which yields step 5.

In step four, you'd divide each side by -2 to isolate x

By dividing both sides by -2, you are using the property of equality and it gets you to the answer in Step 5.

(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
