Answer 1

Answer:

(a+b)^2= a^2 +b^2 + 2× a×b

Answer 2

Answer:

$(a + b)^2 = a^2 + 2ab + b^2$

Step-by-step explanation:

A B whole square can be thought of as either A plus or A minus a B whole square. In algebra, the binomials are expanded using the whole square formulae for $a - b$ and $a + b$. These are referred to as the square of a binomial expansion, we can say. The fundamental algebraic identities $(a - b)^2$ and $(a + b)^2$ are used to simplify numerical statements and binomial equations with variables.

One of the most often used algebraic identities in mathematics is the $(a + b)^2$ formula. Here, let's examine the $a$ plus $b$ whole square formula.

The formula for $(a - b)^2$ can be derived as:

$(a + b)^2 = (a + b)(a + b)$

$= (a)(a) + (a)(b) + (b)(a) + (b)(b)$
Area of square with side $(a +b)$ = Area of square with side “$a$” + Areas of two rectangles + Area of small square

$= a^2 + 2ab + b^2$

$(a + b)^2 = a^2 + 2ab + b^2$
