Question

2
Using identity and given hint , evaluate the
following:
(342)^2 - (341)^2
Hint : (300 + 42)^2 - (300 + 41)^2
Solve by using (a+b)^2 - (a + b)^2
Evaluate by simplifying both terms
separately i.e. (a + b)^2 - (a + b)^2
= (a)^2 + 2ab +(b)^2 - (a)^2 + 2ab + (b)^2​

Answer 1

Step-by-step explanation:

(a + b)^2 - (a + b)^2

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