Question
for the non-nill matrices A and B, which of the following statement is true
A -B = -B +A
A-B = B-A
A/B = B/A
None of the above
Expert Solution
Step 1
Consider the given information.
We will check one by one option.
(a)
A -B = -B +A
The above statement is showing the subtraction of two matrix. Which is always true and the addition of matrix is always commutative.
(b)
A-B = B-A
Step 2
Further simplify the statement.
This implies, A is null but A is not a null matrix.
(c)
A/B = B/A
Further simplify the statement.
It may be true for some matrixes but it is not true for all matrix.
