By solving y = 25 · x² - 100 through the <em>square root</em> method, we conclude that the two roots of the <em>quadratic</em> formula are y₁ = + 2 and y₂ = - 2.
<h3>How to obtain the roots of a second order polynomial </h3>
Herein we have a polynomials of the form y = a · x² - b. By algebra we find that two roots exists, which are described below according to the <em>square root</em> method:
,
If we know that a = 25 and b = 100, then the two roots of the equation are:
y₁ = + 2, y₂ = - 2
By solving y = 25 · x² - 100 through the <em>square root</em> method, we conclude that the two roots of the <em>quadratic</em> formula are y₁ = + 2 and y₂ = - 2.

<span>We will consider all of the options in detail first. Distance is the separation between two points on a plane, and is calculated by squaring the difference in the y and x values, adding them and then taking their square root. A line is a one-dimensional set of points that extends infinitely far in only one dimension. A plane is a flat, two-dimensional surface that extends infinitely far in two dimension. A point is usually an element within the plane being considered. This exists in 0-dimensions. Therefore, the answer is C. plane.</span>
