Answer:

Step-by-step explanation:
Given

The number line is missing from the question.
So, I will answer the question and also draw the number line to show the product.


To represent this on a number line;
We draw a number line of 15 points, and place a dot on the 6th point.
This represents 6/15
See attachment

so.... notice, using the p/q factors, we ended up using 3/1 or just 3, so the root of x = 3, which gives us the factor of x-3 then
then you factor the quadratic, then set f(x) to 0, and solve each for "x"
