The solution of the expression ( 9y² - 4x )( 9y ² + 4x) will be 81y⁴ - 16x².
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression ( 9y² - 4x )( 9y ² + 4x) will be solved as below:-
Use the formula:- ( a + b ) ( a - b ) = a² - b²
a = 9y²
b = 4x
( 9y² - 4x )( 9y ² + 4x ) = ( 9y² )² - ( 4x )²
Therefore, solution of the expression ( 9y² - 4x )( 9y ² + 4x) will be 81y⁴ - 16x².
