If three distinct normal can be drawn to the parabola y2 − 2y = 4x − 9 from the point (2a, b) , then the least integral value of a is
Question
Solution 1
The given parabola equation is y^2 - 2y = 4x - 9.
First, we need to convert this equation into the standard form of a parabola. We can do this by completing the square.
The equation becomes (y-1)^2 = 4(x+2), which is a parabola with vertex at (-2,1) and focus at (-1,1).
