If the discriminant is non-negative, the roots are real. Simple as that! Philip Lloyd
WebWe can think of the first term (½) as a starting place for finding the two roots. Then we see that the roots are located 3/2 from the starting point in both directions. This leads us to … WebIf you graph a quadratic equation that has only complex roots, you will get a parabola that never crosses the X axis. Is there a type of representation or graph on which you can graph such an equation that will show at which points the equation crosses the X axis if, …
WebThe discriminant is \({b^2} - 4ac\), which comes from the quadratic formula and we can use this to find the nature of the roots. Roots can occur in a parabola in 3 different ways as … 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:
