The  difference of squares of two numbers, say a and b, is $a^{2} - b^{2}$. Instead of finding the square of each term, it can be expressed as $a^{2} - b^{2} = (a + b)(a - b)$.

Difference of two squares Calculator calculates the difference of squares using the above formula and gives you the answer.
Steps for finding the difference of squares for two numbers:

Step 1 :  Add a and b.

Step 2 :  Subtract  b from  a.

Step 3 :  Multiply results obtained from step 1 and step 2.

Step 4:
Write the answer.
