n n The polynomial of degree has roots. Some of the roots maybe real and others may be imagery, also there may be multiple roots (eg ) . If tis a real, then the term is a factor of Quadratic Equation 0, x y = The graph of a quadratic function is a parabola. If there are real values of for which the parabola will intersect the X-axis at real roots Consider the quadratic equation n Since the degree of the quadratic is = 2, there are two roots which we designate as and Hence . we can express the polynomial as a, b c We can find the relationships between the coefficients and and the two roots and .
