Answer 1

Answer:

Step-by-step explanation:

lhs solving =( a + b )² = a² + 2ab + b²

(3m+4n)² = 3m² + 2 x 3m x 4n + 4n²

=> 3m² + 4n² + 24mn

rhs solving =( a - b )² = a² - 2ab + b²

(3m-4n)² + 48mn

=> 3m² - 2 x 3m x 4n + 4n² + 48mn

=> 3m² + 4n² - 24mn + 48mn

=> 3m² + 4n² + 24mn

Hence, 3m² + 4n² + 24mn = 3m² + 4n² + 24mn
