Answer:

Question is wrong!

Step-by-step explanation:

Given,

a² + b² = 117

ab = 54

a + b = ?

we know,

(a+b)² = a² + b² +2ab

(a+b)² = 117 + 108

(a+b)² = 225

a + b = 15

a - b = ?

we know,

(a - b)² = a² + b² - 2ab

(a - b)² = 117 - 108

(a - b)² = 15

a - b = √15

a + b / a - b

= 15/√15

= √15
