SOLUTION: The line y=3 intersects the graph of y=4x^2+x-1 at the points A and B. The distance between A and B can be written as squareroot m /n, where m and n are positive integers that do n

Question 909131: The line y=3 intersects the graph of y=4x^2+x-1 at the points A and B. The distance between A and B can be written as squareroot m /n, where m and n are positive integers that do not share any factors than one. Find the value of m-n. Thank you!

The second part of the description seems to mean, and you want m-n; and that distance between x values of the the intersection points is .

The x values,

Distance Between Those x values:

I am stopping here because of the lack of clarity in part of your description, but you may be able to understand what you need from the steps presented.
