Question

Plz solve the problem 2 in the given pic

Answer 1

Answer:

(3x - 1 /3x) and (3x - 1/3x)

Step-by-step explanation:

given expression is 9x^2 +1 /9x^2 -2

the expression is in the form of a^2 +b^2 -2ab where a = (3x)^2 and  

b = (1/3x)^2

now a^2 +b^2 -2ab can be written as  (a-b)^2

where a-b, a-b are the factors.

now the factors are (3x - 1 /3x) and (3x - 1/3x)
