Understanding this process can be beneficial in various mathematical applications, from algebra to calculus. Let’s delve into the stepbystep explanation to demystify the calculation of (AB)^2.
Understanding the Expression
Before we dive into the formula and steps to solve (AB)^2, it’s crucial to grasp the meaning behind this expression. In mathematics, (AB)^2 represents the square of the binomial (AB). This means that we are multiplying (AB) by itself, resulting in a specific algebraic expression that we can simplify further.
Formula for (AB)^2
The formula to calculate (AB)^2 involves a straightforward procedure known as squaring a binomial. Here is the formula:
(AB)^2 = A^2 – 2AB + B^2
By following this formula, you can simplify any expression of the form (AB)^2 by substituting the values of A and B into the equation and performing the necessary operations.
StepbyStep Calculation
Let’s break down the process of solving for (AB)^2 into clear and concise steps:
Step 1: Square the first term (A)
 A^2 = A * A = A^2
Step 2: Calculate the product of the two terms (A and B)
 2AB = 2 * A * B = 2AB
Step 3: Square the second term (B)
 B^2 = B * B = B^2
Step 4: Substitute the results into the formula
 (AB)^2 = A^2 – 2AB + B^2
Step 5: Finalize the calculation
 Replace A^2 with A^2, 2AB with 2AB, and B^2 with B^2 in the formula to obtain the simplified expression.
Example Calculation
Let’s illustrate the above steps with an example calculation:
Given (32)^2:
 A = 3, B = 2
 A^2 = 3^2 = 9
 2AB = 2 * 3 * 2 = 12
 B^2 = 2^2 = 4
 Substitute the values into the formula: (32)^2 = 9 – 12 + 4 = 1
Therefore, (32)^2 = 1.
