Match the factorial to its value.

1. 7!
40,320
2. 5!
720
3. 8!
5,040
4. 6!
120

1.-  5,040

2.- 120

3.-  40,320

4.- 720

Step-by-step explanation:

the factorial of a number is multiplying it by all the integers before it until 1.

Thus, we find the factorial of 7: 7!

1.- 7! = 7*6*5*4*3*2*1 = 5,040

and in this same way we find the other factorials:

2.- 5! =5*4*3*2*1 = 120

3.- 8!=8*7*6*5*4*3*2*1 = 40,320

4.- 6! = 6*5*4*3*2*1 =720

(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
