\(296\times296-204\times204=?\)
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 46000
The expression is a difference of two squares, so the identity \(a^{2}-b^{2}=(a+b)(a-b)\) replaces two large multiplications with one easy one.
\(a=296\), \(b=204\)
\(a+b=500\), \(a-b=92\)
\(500\times92=46000\)
