SOMEONE PLZ HELP ! I am stuck on this and I don’t know how to do it someone please help, thank you !

| 10  -10  1  |

|  1    -2  -4 |

| -8  13 -24|

Step-by-step explanation:

First multiply each element in matrix A, this gives:

| -6  - 2  -3 |

|  1   -6   -4 |

| -4   5    0 |

Now we multiply each element in matrix B by  4, this gives:

| -16  8  -4 |

|  0   -4  0  |

|  4  -8  24 |

Finally subtract  this from the first matrix ( subtracting element by element) gives:

| 10  -10  1 |

|  1    -2  -4|

| -8   13- 24|

2 5/8 is the final answer! : )

(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
