The axis of a parabola is parallel to Y -axis. If this parabola passes through the points \((1,0),(0,2),(-1,-1)\) and its equation is \(a x^2+b x+c y+d=0\), then \(\frac{a d}{b c}=\)
- A \(\frac{5}{8}\)
- B \(\frac{5}{2}\)
- C \(-10\)
- D \(10\)
Answer & Solution
Correct Answer
(D) \(10\)
Step-by-step Solution
Detailed explanation
