What matrix in ℝ2 serves the role of 0 in the real number system? what is that role?

What matrix in ℝ2 serves the role of 0 in the real number system?

What is that role?

The role is additive identity.

Step-by-step explanation:

In the real number system, you can add any number to 0 and the answer is still the same number.

In ℝ2, you can add any matrix (same size) to and the answer is still the same matrix.

This role is called "additive identity".

what are the answear choices to the question.

step-by-step explanation:

(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
