## TOOL: DIFFERENCE OF SQUARES CALCULATOR

#### DIFFERENCE OF SQUARES CALCULATOR

Enter the values of a and b in the formula (a2b2).

9242 = 65

SOLUTION

The result of the subtraction is 65.

ALTERNATIVE SOLUTION

● Use the identity a2b2 = (ab) · (a + b) to calculate the difference of squares.

9242 = (94) · (9 + 4)

● The results of the subtraction and addition operations are 5 and 13, respectively.

9242 = 5 · 13

● The product is 65.

9242 = 65

## INFORMATION

We can calculate the difference between the squares of two numbers using two different methods. In the first method, we directly calculate the squares of the numbers and then perform a subtraction operation between the squares. In the second method, we utilize the identity a2b2 = (ab)(a + b). We can find the difference between the squares by multiplying the difference between the numbers with the sum of them.
