Answer 2

To Find :- Expand the following :- (a + b)² ?

Solution :-

(a + b)² can be written as (a + b)(a + b) . Now it can be expended as follows :-

→ (a + b)(a + b)

→ a(a + b) + b(a + b)

→ a * a + a * b + b * a + b * b

→ a² + ab + ba + b²

→ a² + ab + ab + b² { commutative property of multiplication, ba = ab }

→ a² + 2ab + b² (Ans.)

therefore, (a + b)² can be expended as (a² + 2ab + b²) .

Direct formula :-

→ (a + b)²

→ a² + 2ab + b²
