497 by 2 + (x+18) × 1+34 =587

497 by 2 + (x+18) + 34 = 587

497 by 2 + x + 18 + 34 = 587

497 by 2 + x + 52 = 587

601 + 2 x = 1174

2 x = 1174 - 601

2 x = 573

x = 573 by 2

x = 286 1 by 2 , x = 286.5

Step-by-step explanation:

by = /

you can write it as

497

___

2

or

1

_

2

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

(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
