My kitchen clock is working properly but was showing 14:02, which I know is the wrong time, when I left to walk to my friend’s house for coffee. My friend’s clock, which is correct, was showing 14:25 when I arrived and 15:08 when I left. I walked home at the same speed as when I went, and when I arrived home my clock was showing 15:56. I then adjusted my clock to the correct time. How many minutes and which direction did I have to adjust my clock?

Step-by-step explanation:

∞ this is your sign

(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
