love the pfp btw
Step-by-step explanation:
The statement "10x^2 − 9y^2 is not the difference of two squares" is true. The correct explanation for this statement is that the expression 10x^2 − 9y^2 cannot be expressed in the form (a^2 - b^2) where a and b are expressions involving x and/or y.
To be the difference of two squares, an expression must be of the form a^2 - b^2, where a and b are expressions that can be squared. In this case, the expression given is 10x^2 − 9y^2. To express it as the difference of two squares, you would need to factor it into the form (a^2 - b^2), which is not possible without additional terms or variables. Therefore, the given expression cannot be considered the difference of two squares.
