Question

factorize a²-b²+a²-b²​

Answer 1

Step-by-step explanation:

a² - b²is a special case for factoring.  It is called the difference of squares. When factoring the binomial a² - b², we no longer use a table, because there is a simpler way to complete the factoring.  Since it is a difference ( +  -) of perfect squares, you can take the square root of each term.
