- x^2 + 25, no as it is a sum of squares
- 4x^2 - 25, yes
- 9x^2 - 16, yes
- x^2 - 50, no as 50 is not a perfect square
- x^2 - 81, yes
- x^2 - 100, yes
Answer:
Difference of squares method is a method that is used to evaluate the difference between two perfect squares.
For example, given an algebraic expression in the form:
