Emily could start with the quadratic equation
... (2x+5)(2x+6)=31
... 4x² +22x +30 = 31
And then subtract the right side to put it into standard form.
... 4x² +22x -1 = 0 . . . . . . corresponds to the first selection
prime #is when there is only 1 set of numbers that you can multiply to get that number
so it could be 127 because it is prim and only 1x127 woeks
