Line y=mx-3 does not intersect the ellipse whose equation is x^@ + 2y^2 = 2.

by considering an appropriate quadratic eqn in x, find the range of values of m.

this seems to be an easy qn but im stuck with it. help please!!

Hint: Substitute for

*y*into the equation of the ellipse to get a quadratic in*x*, for which the discriminant must be negative.
