Jamie is spinning a five-sided spinner that has different coloured sections. He spins it 100 times and calculates the relative frequency of it landing on red after every 10 spins.

His results are shown in this graph:

If the spinner is fair, how many sides of the spinner are red?

(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

4x and 6y

im not sure though

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
