(2x + 9y) ( 2x - 9y)
To find :-
Product
Formula
It is in form of (a + b) ( a - b ) = a²-b²
By using this identity we can solve this problem
Solution:-
(2x + 9y) ( 2x -9y)
(a+b)(a-b) = a²-b²
Similarly,
(2x + 9y) ( 2x -9y) = (2x)² - (9y)²
(2x + 9y) ( 2x -9y) = 4x² - 9y²
So , Required answer is 4x²-9y²
