Question

How to factor difference of two squares?

Answer 1

??

Answer 2

\[(x+y)(x-y)=x^2-y^2\]

Answer 3

\[\left( a + b \right) \left( a - b \right) = a{^2} - b{^2}\]

The factors of \[a{^2} - b {^2}\] are (a + b) and (a - b)


* Remember: The algebraic term is a perfect square when the numerical coefficient (number in front of the variables) is a perfect square. Then the exponents of all variables are even numbers.
