Step-by-step explanation:
Let the age of boy be ( x ) years and age of his brother be ( 25 - x ) years
Product of their ages = 126
=> x ( 25 - x ) = 126
=> 25x - x² = 126
=> x² - 25x + 126 = 0
=> ( x - 18 ) ( x - 7 ) = 0
=> x = 18 or 7
Hence, age of boy = x = 18 or 7 years
Age of his brother = ( 34 - 18 = 16) or ( 34 - 7 ) = 27 years
