Answer 2

$\underline{\mathfrak{\huge{The\:Question\:asked:}}}$

Using the identity for difference of two squares, find the value of :

$\tt{203^{2} - 197^{2}}$

$\underline{\mathfrak{\huge{Here's \:Your\:answer:}}}$

The identity which will be applicable for this question is :

$\sf{a^{2} - b^{2} = (a-b) (a+b)}$

Here, we can put the value of :

a = 203

b = 197

Now, keep these values in the formula and then solve it :-

$\tt{203^{2} - 197^{2} = (203 - 197) (203 + 197)}$

Solve this formed equation further

=》 $\tt{203^{2} - 197^{2} = 6 \times 400}$

Last one step to go

=》 $\tt{203^{2} - 197^{2} = 2400}$

There's your answer ! It's 2400.
