Step-by-step explanation:
Assuming that the equation is:
I graphed the given equation on a graphing calculator.
The roots of a quadradic equation are the x-intercepts of the function.
On the graph the parabola intercepts the points (-4.871, 0) and (-1.129, 0).
Therefore, -4.871 and -1.129 are the roots to the equation.
If we used the quadradic formula...Hope this helps you.
