A) Equal
B) Equal in magnitude but opposite in sign
C) Reciprocal to each other
D) None of these
Correct Answer: A
Solution :
Coefficient of \[{{x}^{p}}\] is \[^{(p+q)}{{C}_{p}}\] and coefficient of \[{{x}^{q}}\] is \[^{(p+q)}{{C}_{q}}\]. But \[^{(p+q)}{{C}_{p}}={{\,}^{(p+q)}}{{C}_{q}}\], \[(\because {{\,}^{n}}{{C}_{r}}={{\,}^{n}}{{C}_{n-r}})\].You need to login to perform this action.
