Question

The locus of point of intersection of two
normals drawn to the parabola y' = 4ax
which are at right angles is
1) y? = a(x-3a)
2) y2 = a(x--a)
3) y? = 3a(x - 2)
4) y = 2a(x - 2)
The equation of the common tangent to
the parabola y = x’ and y = -(x - 2) is
1) y = 4(x-1) 2) x = 0
3) y=-4(x - 1) 4) y = 30x-50
If from a point A, the two tangents draw​
