Please help I really CANNOT get this wrong so pls:
2x-7-5(4x-7)

Step-by-step explanation:

2x - 7 -5(4x-7)

2x - 7 -20x + 35

-18x + 28  

-18x + 28

Step-by-step explanation:

2x-7-5(4x-7)

1. Distributive Property

2x - 7 - 5*4x - 5*-7 ( 2 negatives make a positive)

2x - 7 - 20x + 35

2. Combine like terms

2x - 7 - 20x + 35

-18x + 28

you cannot simplify it anymore

(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
