Equation of the normal to the curve \(y=x^2+x\) at the point \((1,2)\) is
- A \(x-3 y+5=0\)
- B \(x+3 y+7=0\)
- C \(x+3 y+5=0\)
- D \(x+3 y-7=0\)
Answer & Solution
Correct Answer
(D) \(x+3 y-7=0\)
Step-by-step Solution
Detailed explanation
\(y=x^2+x \Rightarrow \frac{d y}{d x}=2 x+\left.1 \Rightarrow \frac{d y}{d x}\right|_{(1,2)}=3\) Equation of normal at \((1,2)\) is…
