WebIn terms of the fundamental theorem, equal (repeating) roots are counted individually, even when you graph them they appear to be a single root. You have to consider the factors: x^3 (ax^2 + bx + c) If x^3 = 0, this is the same thing as x * x * x = 0, or x = 0, x = 0, x = 0. WebThe roots of a quadratic equation are the 𝑥-coordinates of the points on the graph that have 𝑦-coordinates of zero, so the 𝑥-values in the equation that generate a 𝑦-value of zero — in other …

Roots in a graph

WebThe roots of a quadratic are the values of x where the quadratic equals 0, so if y= ax^2+bx+c then the roots of ax^2+bx+c are the values of x when y=0. When the quadratic is graphed, the roots are the points on the graph where it crosses the x … WebWe have a quadratic function with complex roots ( ) = 2−2 +5 or ( )= ( −1)2+4. The minimum point (vertex) of the graph is at 𝑉(1,4), see Figure 1, so it doesn’t cross the x-axis. Because it lies entirely above the x-axis, we know it has no real roots. The discriminant is:
