Question

"For a given?parabola?and a given point (h, k), this cubic in m has
three roots say m1, m2, m3?i e from (h, k) three?normals?can be
drawn to the parabola whose slopes are m1, m2, m3 For this cubic,
we have m1?+ m2?+ m3?= 0, m1?m2?+ m2?m3?+ m3?m1?= (2a ? h)/a and
m1?m2?m3?= ?k/a " 1 Derive m1?m2?+ m2?m3?+ m3?m1?= (2a ? h)/a 2
Derive m1m2m3=-k/a
