The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that
has at least two real roots
The equation is given as: 
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of 
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that
crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
This means that
has at least two real roots

Answer:
2
16yx + 8yx - 8y
Step-by-step explanation:
The answer is 73 because , 5+8=13 black times 4=52 red so
8 blue + 13 black + 52 red = 73 markers in all
