Question:medium
If \( \sin \alpha \) and \( \cos \alpha \) are the roots of the equation \( ax^2 + bx + c = 0 \), then
If \( \sin \alpha \) and \( \cos \alpha \) are the roots of the equation \( ax^2 + bx + c = 0 \), then
Show Hint
Always use trigonometric identities when roots involve sine and cosine.

- \( a^2 - b^2 + 2ac = 0 \)
- \( (a-c)^2 = b^2 + c^2 \)
- \( a^2 + b^2 - 2ac = 0 \)
- \( a^2 + b^2 + 2ac = 0 \)
- \( a + b + c = 0 \)
Show Solution
The Correct Option is D
