Q65.The sum of the co-efficient of all even degree terms in ๐ฅ in the expansion of 6 6 ๐ฅ+ โ๐ฅ3 - 1 +๐ฅ- โ๐ฅ3 - 1 , ๐ฅ> 1 is equal to (1) 26 (2) 32 (3) 24 (4) 29
What This Question Tests
The question tests the application of the binomial theorem for the sum of two binomial expansions and then requires careful identification and summation of coefficients of terms with even degrees.
Concepts Tested
Formulas Used
(A+B)^n + (A-B)^n = 2 * [C(n,0)A^n + C(n,2)A^(n-2)B^2 + ...] (for even n)
