We want to solve an equation by graphing it.
The estimated solutions are:
x = -1.1
x = 3.6
Let's see how to get those.
The equation we want to solve is:
-2x^2 + 5x + 8 = 0
To solve this graphically, we need to graph the function:
y = -2x^2 + 5x + 8
The graph of this function can be seen below.
The solutions of the equation:
-2x^2 + 5x + 8 = 0
Are given by the intersections between the graph and the x-axis.
These are (estimatives):
x = -1.1
x = 3.6
