Answer 1

QUESTION:

Solve the following sum 102^2 - 104^2.

ANSWER:

We use the identity here;

${x}^{2} - {y}^{2}$

the expansion of the identity is;

$(x + y)(x - y)$

now come to main question ;

${(102)}^{2} - {(104)}^{2}$

so, we assume that

$102 = x \\ \\ \\ 104 = y$

using the identity;

$(102 + 104)(102 - 104) \\ 206 \times ( - 2) \\ - 412$

FINAL ANSWER :

$\huge\red{ - 412}$
