(i) Step 1
R1 = R1 + R2 + R3
Step 2
(5x+4) common in R1, bring that out, you are left with all 1s in R1
Applying C2 → C2 − C1, C3 → C3 − C1, we have:
Step 3
R2 = R2 - 2x(R1)
R3 = R3 - 2x(R1)
Now matrix is :
(5x+4)[(1,1,1),(0,4-x,0),(0,0,4-x)]
=(5x+4)(4-x)(4-x)
Expanding along C3, we have:
Hence, the given result is proved.
(ii) Here you need to subtract y(R1) from R2 and R3.
Applying R1 → R1 + R2 + R3, we have:
Applying C2 → C2 − C1 and C3 → C3 − C1, we have:
