AB will be an Identity matrix.
<h3>
What is an identity matrix?</h3>
- A square matrix with 1s on the main diagonal and 0s everywhere else is an identity matrix.
- The identity matrices 22 and 33, for example, are presented below.
- These are known as identity matrices because they produce the identity matrix when multiplied by a compatible matrix.
- If the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
- When the matrix is multiplied by the original matrix, the result is the identity matrix.
As it is given in the description itself, if the answer to a matrix multiplication problem is an identity matrix, then each of the two matrices is an inverse matrix of the other.
Therefore, AB will be an Identity matrix.

First you need to get a common denominator. The first two problems already have a common denominator, so you just have to find the sum and difference of the two problems, respectively.
6.) (9y-3)/(y^2-5)
8.) 3/xy^3
Two find a common denominator, find the smallest value that has BOTH denominators as factors.
10.) 8x^3*y^3 is the common denominator
Answer: 2/(8*x^3*y^3)
12.) Factor x^2 + 4x + 4 to get (x+2)(x+2)
Therefore, x+2 is already part of x^2 + 4x + 4
(x+4)/(x^2+4x+4)
14.) Factor both denominators..
4(y+2) and y(y+2)
So the common denominator would be 4y(y+2)
The first fraction is missing a "y" so multiply the numerator by y to get y^2
The second fraction is missing a "4" so multiply the numerator by 4 to get 4
(y^2 - 4)/(4y(y+2))
So can factor the numerator to get (y+2)(y-2). There if a (y+2) on top and bottom so they cancel out.
Answer: (y-2)/4y
