The Quadratic Eq;n , when plotted on gaph paper, will reveal a parabola.

This patrabola can intersect the x-axis in two places, just touch the x-axis or miss it altogether.

The roots of a quadratic eq;n are the point(s) were the parabola intersects the x-axis.

If is intersects at two points, then there are two roots. If it just touches the x-axis, then there is one root only. If it does not touch the x-axis, then the eq'n remains unresolved.
