Question

If A = `[(5, -5),(3, -3)]` and B = `[(-5, 5),(-3, 3)]`; the value of matrix (A – B) is ______.

विकल्प

• `[(0, 0),(0, 0)]`

• `[(10, -10),(6, -6)]`

• `[(10, -10),(-6, 6)]`

• `[(-10, 10),(-6, 6)]`

Answer 1

If A = `[(5, -5),(3, -3)]` and B = `[(-5, 5),(-3, 3)]`; the value of matrix (A – B) is `underlinebb([(10, -10),(6, -6)])`.

Explanation:

A – B = `[(5, -5),(3, -3)] - [(-5, 5),(-3, 3)]`

= `[(5 + 5, -5 - 5),(3 + 3, -3 - 3)]`

= `[(10, -10),(6, -6)]`
