Question

if the graph of a polynomial intersect the x-axis at exactly two points , is it necessarily a quadratic polynomial​

Answer 1

can be a quadratic polynomial

Step-by-step explanation:

Answer 2

If a polynomial of degree three has two equal and one unequal root, the graph would encounter the coordinate axis at two points.

• thus the polynomial whose graph intersects the x-axis at two places needn't be a quadratic polynomial.
• once the graph line of a polynomial intersects the x-axis at precisely two points, it implies that the polynomial has two equal roots or larger than two roots. Therefore, it can not be a quadratic polynomial.
• once 2 zeroes of a polynomial are equals, then two decussate points coincide to become one point.
• The graph of a quadratic polynomial may be a parabola.
• the form of a quadratic polynomial is either an upward or downward U - formed curve i.e., Associate in Nursing upward or downward parabola.
• Also, the graph of the quadratic cuts the X - axis at the foremost at two points
