Step-by-step explanation:
Given
÷ 
The first step is to factor numerators/denominators, if possible
x² - 4 = (x - 2)(x + 2) ← difference of squares
x² - 4x + 4 = (x - 2)(x - 2) ← perfect square
4x + 2 = 2(2x + 1)
To divide the expressions follow the steps
• Leave the first fraction
• Change division to multiplication
• Turn the second fraction upside down
We now have
× 
Final step is to cancel common factors from the numerators/denominators
=
← quotient
