$3$ distinct normals to the given parabola

54 Views Asked by At

If $(h,k)$ be the point on the parabola $\displaystyle (x-1)^2+(y-1)^2 = \frac{(x+y+2)^2}{2}$ from where $3$

Distinct normal can be drawn to the parabola, Then $\min$ positive integer value of $h$

Here $(1,1)$ be the focus of the parabola and $x+y+2=0$ be the equation of directrix,

Now how can i calculate equation of parabola in standard form, Help Required, Thanks
