Help is needed plz. I'll give 15 points !

Answer 1

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  

Answer 2

.............X≠3 and X≠1..............
