Answer: 5/9
Easy
f(x)/g(x)
replace
(-2x^3+x^2+16x-15)/(x+3)
you can simlify this to get
-2x^2+7x-5
Not the greatest example, but the only way I could really show you what the graph looks like. Hope it helps
Try it.
8 =? 2*8 - 4
8 =? 16 - 4
8 =? 12
8 is not a solution of the original equation
Try 4
4 = 2*4 - 4
4 = 8 - 4
4 = 4 and yes 4 works.
4 is unique. No other solution will work.
