Answer to Problem 44HP
The roots of the quadratic equation, when represented on a graph, intercept on the x-axis.
Explanation of Solution
Given information :
The roots of the quadratic equation.
When a quadratic equation is represented on a graph, the curve is parabolic in nature. It may be an upward parabolic curve or a downward parabolic curve.
The roots of the said equation always intercept on the x-axis. If there are two roots, they intercept twice, if there is one root, the curve intercepts once. If there no roots or they are imaginary, the curve does not intercept at the x-axis.
The points where the roots intercept the x-axis, are known as zeros and their points are represented in the form of
