Q66.The sum of the co-efficient of all odd degree terms in the expansion of 5 5 + , (x > 1) is (x + √x3 −1) (x −√x3 −1) (1) 2 (2) −1 (3) 0 (4) 1
What This Question Tests
This question combines algebraic simplification using the difference of squares identity with the application of the binomial theorem to find the sum of coefficients of odd degree terms in a specific expansion.
Concepts Tested
Formulas Used
(a+b)^n + (a-b)^n = 2 * [T_even]
(a+b)^n - (a-b)^n = 2 * [T_odd]
