Answer:
x
Step-by-step explanation:
We need to solve this equation by graphing. We need to find what roots will make our equation equal zero. This is the same as drawing a line
and see what points intercepts both graphs.
According to the graph above, one root are between 0 and 0.5 and the other are between 4 and 4.5.
We can find it actual value by solving it
Apply Quadratic Formula, we get
and
Which gives us approximately
x=4.27 and 0.23
