Complex conjugate roots:
suppose that the equation ax^2+bx+c=0 has real coefficients and the
complex roots. why must the roots be complex conjugates of each
other?

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
