The rank of the matrix is then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given that Rank of the matrix 42(1-x)5k163(1+x) is 1. We know that, Rank of Matrix is number of non-zero rows of a matrix in its echelon form. Applying R3→R1+R3 ⇒42(1-x)5k11052 Now, Applying R3→R3-2R2 ⇒42(1-x)5k105-2k0 Now, Applying R2→R2-54R1…
