There re 50 beads in a pot. Some of the beads are blue. The experimental probability of taking a blue bead at random from the pot is 0.4. work out an estimate of the number of blue beads in a pot.

(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

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
