Ex 3.4, 1 - Find inverse of [1 -1 2 3] - Chapter 3 Class 12
Ex 3.4, 1 Find the inverse of each of the matrices, if it exists. [ 8(1&−1@2&3)]Let A = [ 8(1&−1@2&3)]We know that A = IA [ 8(1&−1@2&3)] = [ 8(1&0@0&1)] AR2 → R2 – 2R1 [ 8(1&−1@𝟐−𝟐(𝟏)&3−2(−1))] = [ 8(1&0@0−2(1)&1−2(0))] A [ 8(1&−1@𝟎&5)] = [ 8(1&0@−2&1)] AR2 →1/5 R
