The number of terms in the expansion of ( (x²+y² )²⁵- (x²-y² )²⁵ ) after simplification is

Options

  1. A( 13 )
  2. B( 50 )
  3. C( 00 )
  4. D( 26 )

Correct answer

A. ( 13 )

Step-by-step solution

(A) ( (a+b)^ n -(a-b)^ n ) if ( n ) is odd On simplification we get ( n+1 2 ) terms i.e., ( 25+1 2 =13 ) terms
