The solutions of the quadratic equation are estimated as:

x = -0.21

x = 1.21

How to use the graph to find the roots?

The graph of the quadratic equation:

y = 4x² - 4x - 1

is in the image at the end.

We want to use this graph to find the solutions of the equation:

4x² - 4x - 1 = 0

To do so, just identify the values of x at which the parabola intercepts the horizontal axis.

Using the graph, we can see that the two intercepts are at:

x = -0.21

x = 1.21
