As you know, the zeros of a quadratic polynomial are precisely the x-coordinates of the point where the parabola representing the polynomial intersects the x-axis. A quadratic polynomial can have either two distinct zeros, or two equal zeros (i.e., one zero) or no zero in real numbers.
For which value of 'x', does the function f(x) become zero can be explored through this geogebra applet.
