x ≠ 1 and x ≠ 3 are the two restrictions
Step-by-step explanation:
- Step 1: In the given expression, the denominators are x - 1 and x - 3. If the denominators become zero, the answer cannot be defined.
A number divided by zero cannot be defined, so the denominators cannot be zero.
⇒ x - 1 = 0
∴ x = 1
⇒ x - 3 = 0
∴ x = 3
So these are the two restrictions, x ≠ 1 and x ≠ 3
