Firstly it's not a radical expression.

You can factorize the numerator x²+12x+36 = (x+6)²

Factorize the denominator 12x+72 = 12(x+6)

=(x+6)² / 12(x+6) , simplify. Answer = (x+6)/12

Answer:

7 : 1

Step-by-step explanation:

Total money = $96
Contribution ratio = 3 : 5 : 8

Contribution by each:

3x + 5x + 8x = 96
16x = 96
x = 6
3x → $18, 5x → $30, 8x → $48

Equal contribution is:

$96/3= $32

Returned by first and second person:

$32 - $18 = $14
$32 - $30 = $2

Ratio of returned amount:

14 : 2 = 7 : 1
