Answer :
Step-by-step explanation:
Given: (a+b)²
To prove: (a+b)² = a² + 2ab + b²
Proof:-
(a+b)² = (a+b)(a+b)
(a+b)²=a(a+b)+b(a+b)
(a+b)² = a²+ab+ab+b²
(a+b)² = a²+2ab+b².
Step-by-step explanation:
Given: (a+b)²
To prove: (a+b)² = a² + 2ab + b²
Proof:-
(a+b)² = (a+b)(a+b)
(a+b)²=a(a+b)+b(a+b)
(a+b)² = a²+ab+ab+b²
(a+b)² = a²+2ab+b².
