Expert Solution
Step 1

Given expression:

4х
Зх
х2 + 4x — 5 х2 +x — 2
To Find: Subtract given expression.
Step 2

Begin with factorizing the denominator,

Зx
4x
х2 + 5х — х —5
4x
х2 + 2х — х — 2
Зx
x(x+5) – 1(x + 5)
4х
x(x+2) – 1(x+2)
Зx
(x – 1)(x + 5)
(x – 1)(x+ 2)
Next, determine the LCM of the denominator,
The LCM of the denominators is (x – 1)(x + 5)(x+2).
