About Perfect Square Formula
The perfect square formula is used to calculate the square of the addition or subtraction of two terms, (a ± b)2. In the following section, we'll go through the perfect square formula in further depth.
What is the Perfect Square Formula?
When we need to calculate the square of any binomial, we use the perfect square formula. It can be used to factorise or calculate the square of the sum or difference of two terms. The formula for a perfect square is:
(a ± b)2 = (a2 ± 2ab + b2)
(a + b)2 = (a2 + 2ab + b2)
(a - b)2 = (a2 -2ab + b2)
