AP EAMCET · Maths · Pair of Lines
The point of intersection of the pair of lines \(x^2+x y+2 y^2-3 x+2 y+4=0\) is
- A \((1,2)\)
- B \((-1,2)\)
- C \((-2,1)\)
- D \((2,-1)\)
Answer & Solution
Correct Answer
(D) \((2,-1)\)
Step-by-step Solution
Detailed explanation
The point of intersection of the pair of lines \(f(x, y) \equiv x^2+x y+2 y^2-3 x+2 y+4=0\) is same as the intersection of curve obtaining after partial differentiating of the curve w.r.t. \(x\) and \(y\) respectively.…
