Answer:

the roots of this quadratic expression are: x = -1 and x = 4

Step-by-step explanation:

You need to find at which x-values the graph crosses the x-axis (this is when y = 0, and therefore the roots of the quadratic equation represented via the graph).

In our case notice that the graph crosses the x-axis at the points:

x = -1 (on the left), and x = 4 (on the right)

Therefore the roots of this quadratic expression are: x = -1 and x = 4.
