The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
x = 0
An equation crosses the horizontal axis at points where the output value (usually represented by (y)) is zero. These points are known as the roots or x-intercepts of the equation. To find these points, you set the equation equal to zero and solve for the variable, typically represented as (x). Graphically, this represents the points where the graph of the equation intersects the x-axis.
It can be casually called the x intercept, but it/they is/are the root(s) of the function represented by the graph
Where a line crosses the y an x axis on a graph.
They are all the points where the graph crosses (or touches) the x-axis.
The real solutions are the points at which the graph of the function crosses the x-axis. If the graph never crosses the x-axis, then the solutions are imaginary.
Whether the graph has 0, 1 or 2 points at which it crosses (touches) the x-axis.
The zeros of a polynomial represent the points at which the graph crosses (or touches) the x-axis.
It is at point of origin which is at (0, 0)
For a line, this is the x-intercept. For a polynomial, these points are the roots or solutions of the polynomial at which y=0.
-- The roots of a quadratic equation are the values of 'x' that make y=0 . -- When you graph a quadratic equation, the graph is a parabola. -- The points on the parabola where y=0 are the points where it crosses the x-axis. -- If it doesn't cross the x-axis, then the roots are complex or pure imaginary, and you can't see them on a graph.

It is the x intercept
The x- and y-intercepts of a function are the points at which the graph of the function crosses respectively the x- and y-axis (ie. y=0 and x=0).
A root is the value of the variable (usually, x) for which the polynomial is zero. Equivalently, a root is an x-value at which the graph crosses the x-axis.
