If and are the roots of the equation , then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given, tan15° and tan30° are the roots of the equation x2+px+q=0, So, sum of roots will be tan15°+tan30°=-p ....1 And product of roots will be tan15°tan30°=q ....2 Now we know that tanA-B=tanA-tanB1+tanAtanB Using the above formula…
