(a – b)2 =a2 – 2ab + b2
There is a way to calculate the square root of the differences between two integers using the equation (a + b)2 employed to expand the binomial term once you square it.
It is essential to find how to calculate (a + b)2 by following the steps:
(a – b)2 = (a – b)(a – b)
= (a)(a) – (a)(b) – (b)(a) + (b)(b)
= a2 – 2ab + b2
The proof of a minus whole square formula
Think about a square having lengths on the sides that are “a” and an area that can be represented by “a2” when multiplied together.
Make a tiny square of this and ensure the side is the number (a + B). This means that we’ll end in two rectangles. One is horizontal, and the other one is vertical.
Let’s add all the areas of these three quadrilaterals.
The square’s surface that has a side of (a – (b) will be equal to (a – (b) square.
The vertical area (rectangle) can be calculated in the following manner Area = Length X Breadth = ab.
The size of the vertical strip (rectangle) is equal to length divided by width, which is (a – (b) divided by width. That is equal to b(a (a – B).
The square’s area with”a” on the sides “a” equals the area of the square with one side (a – B) plus the respective areas of both rectangles.
a2 = (a – b)2 + ab + b(a – b)
a2 = (a – b)2 + ab + ab – b2
a2 = (a – b)2 + 2ab – b2
Therefore, (a – b)2 = a2 – 2ab + b2

What is the method by which this identity of 2 – 2 = 2 = (a + b) (a + B) is derived:
Take RHS of the name:
(a + b) (a – b)
Multiply by multiplying two binomials, and you obtain:
= a(a – b) + b(a – b)
= a2 – ab + ab – b2
Solve similar terms, and we will get the following:
= a2 – b2
In this way, we get our identity i.e. a2 – b2 = (a + b) (a – b)
Below are a few examples of this kind of identity.
Example 1: Solve 3a 2 – 2b 2
Solution: This proceeds as follows:
Given polynomial 3a 2 – 2b 2 represents identity third, i.e., a 2 – b 2
Where a = 3a and b = 2b
Now apply values of a and b on the identity, i.e., a 2 – b 2 = (a + b) (a – b), and we get:
3a 2 – 2b 2 = (3a + 2b) (3a – 2b)
Hence, 3a 2 – 2b 2 = (3a + 2b) (3a – 2b)
Example 2: Solve (6m + 9n) (6m – 9n)
Solution: This is as follows:
Polynomial (6m + 9n) (6m 9n) is an the identity third i.e. a2 – b2
Where a = 6m and b = 9n
Apply the values of both a and b to this identity, i.e., A 2 2 2. + (a + b) (a + B), and we will get:
(6m + 9n) (6m – 9n) = (6m)2 – (9n)2
The exponential forms can be expanded on the LHS, and we’ll get the following:
= 36m2 – 81n2
Hence, (6m + 9n) (6m – 9n) = 36m2 – 81n2
How do you calculate the equation for the formula a minus b minus square?
The (a + b + c) 2 formula is among the most essential algebraic identities. It can be read as a less b plus c in a square. The (a – b – c)2 formula is written as (a – b – c)2 = a2 + b2 + 2ab + 2bc 2ca.
Answer This formula: a2 +”b2″ is commonly known as “the difference of squares formula.”
A square divided by b can be used to determine the differences between two squares without computing the squares themselves. a2-b2=(a+b)(a-b).
The logic behind this formula is straightforward.

Where a = 3a and b = 2b
Now apply values of a and b on the identity, i.e., a 2 – b 2 = (a + b) (a – b), and we get:
3a 2 – 2b 2 = (3a + 2b) (3a – 2b)
Hence, 3a 2 – 2b 2 = (3a + 2b) (3a – 2b)
Example 2: Solve (6m + 9n) (6m – 9n)
Solution: This proceeds as follows:
Given polynomial (6m + 9n) (6m – 9n) represents identity third i.e. a 2 – b 2
Where a = 6m and b = 9n
Now apply values of a and b on the identity, i.e., a 2 – b 2 = (a + b) (a – b), and we get:
(6m + 9n) (6m – 9n) = (6m) 2 – (9n) 2
Expand the exponential forms on the LHS, and we get:
= 36m 2 – 81n 2
Hence, (6m + 9n) (6m – 9n) = 36m 2 – 81n 2
