Apply the given elementary transformation of the following matrix.
A = `[(1,2,-1),(0,1,3)]`, 2C2
B = `[(1,0,2),(2,4,5)]`, −3R1
Find the addition of the two new matrices.
उत्तर
A = `[(1,2,-1),(0,1,3)]`
By 2C2, we get,
A ∼ `[(1,4,-1),(0,2,3)]`
B = `[(1,0,2),(2,4,5)]`
By −3R1, we get,
B ∼ `[(-3,0,-6),(2,4,5)]`
Now, addition of the two new matrices
= `[(1,4,-1),(0,2,3)]+[(-3,0,-6),(2,4,5)]`
= `[(-2,4,-7),(2,6,8)]`
