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.

A polynomial is an expression of various exponentials of a variable wich may or may nor have coefficients and constants. The coefficients may have a radical, square root, cube root etc, but not the variable. A radical expression is any expression involving square roots, cube roots, etc. These may have the variable inside the radical but do not have to have them. sq root (5) is a radical expression, so is sq root (x) 3x2 + 2x - 9 is a polynomial, so is x + sq root (5)
