Question
If A = `[(1, -1, 3), (2, 5, 4)]`, then R1 ↔ R2 and C3 → C3 + 2C2 gives ______
Options
`[(2, -5, 14), (1, 1, -1)]`
`[(2, 5, 14), (1, -1, 1)]`
`[(2, -5, 14), (1, -1, -1)]`
`[(2, 5, 14), (1, -1, 2)]`
MCQ
Fill in the Blanks
Solution
`[(2, 5, 14), (1, -1, 1)]`
Explanation:
A = `[(1, -1, 3), (2, 5, 4)]`
Applying R1 ↔ R2, we get
A = `[(2, 5, 4), (1, -1, 3)]`
Applying C3 → C3 + 2C2, we get
A = `[(2, 5, 14), (1, -1, 1)]`
