If (p ) + (q ) = 0 and p q , then the general value of (where n is any integer) is...
Options
- A(3n+1) p - q
- B(2n+1) p q
- C(n 1) p q
- D(n+2) p + q
Correct answer
B. (2n+1) p q
Step-by-step solution
Given (p ) + (q ) = 0 Using the formula C + D = 2 ( C+D 2 ) ( C-D 2 ) : 2 ( p+q 2 ) ( p-q 2 ) = 0 This implies either ( p+q 2 ) = 0 or ( p-q 2 ) = 0 If ( p+q 2 ) = 0 , then p+q 2 = (2n+1) 2 , where n is an integer. = (2n+1) p+q If ( p-q 2 ) = 0 , then p-q 2 = (2n+1) 2 , where n is an integer. = (2n+1) p-q Combining both cases, the general value of is (2n+1) p q Answer: (2n+1) p q
