Q59 of 128 Page 224

State whether the statements are true (T) or false (F).

(a + b)2 = a2 + b2

Lets recall the formula of (a + b)2.

(a + b)2 = a2 + 2×a×b + b2


⇒ (a + b)2 = a2 + 2ab + b2


But right-hand side of the equation does not match left-hand side of the equation.


That is,


a2 + 2ab + b2 ≠ a2 + b2


⇒ (a + b)2 ≠ a2 + b2


Hence, this statement is false.
