use graph to find delta, u can draw out the graph which is simple, the 4x-1 is squared, it's just i couldn't fit the square root on it all,

now, the coordinates are 2,3 and 3 goes to 3.5 and 2.5

now here's where i get stuck, what do i do with the absolute value of square root 4x-1, because i plug in 3.5 and 2.5 and subtract those with 2 and there not even close to the answer which is 1.44
