The point of intersection of lines denoted by \(3 x^2-11 x y+10 y^2-7 x+13 y+4=0\) is
- A \((3,1)\)
- B \((1,3)\)
- C \((0,0)\)
- D \((-3,-1)\)
Answer & Solution
Correct Answer
(A) \((3,1)\)
Step-by-step Solution
Detailed explanation
Equation of given lines \[ f(x, y) \equiv 3 x^2-11 x y+10 y^2-7 x+13 y+4=0 \] The point of intersection of line is same as the point of intersection of lines \(\frac{\partial f}{\partial x}=0\) and \(\frac{\partial f}{\partial y}=0\)…
