Answer 2

Answer:

it's simple , we have to use algebraic identity

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

so here we have to find A and B such that in both the situations A=A and B=B

therefore keeping that in mind A = 150 and B = 46

then A+B = 196 (as given in question)

and A-B = 104 (as given in question)

therefore (150+46) (150-46) = 150^2 - 46^2

therefore 150^2 = 22500

therefore 46^2 = 2116

therefore 22500 - 2116 = 20384

to tally , multiply 104 and 196

i.e. 104×196 = 20384
