Answer 2

Answer ➡

(a + b )^2

is a standard algebraic formula

formula of (a + b) ^2

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

way to prove it,

we know the square of any number is the multiplication of this number with itself

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

= a^2 + ab + ba + b^2

= a ^2 + ab ( 1 + 1) + b^2

= a^2 + 2ab + b^2

⚫Hence our formula is

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