Answer:

The (a + b)² formula is the algebraic identity used to find the square of the sum of two numbers. i.e., it is used to find the square of a binomial a + b. The formula of (a+b) whole square says (a + b)2 = a² + 2ab + b².

Answer:

(a + b)² = a² + 2ab + b².

Step-by-step explanation:

To prove this formula, we will just multiply (a + b) (a + b).

(a + b)² = (a + b)(a + b)

= a (a + b) + b (a + b)

= a² + ab + ba + b² (by distributive property)

= a² + 2ab + b²

So, (a + b)² = a² + 2ab + b².
