Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
[(4x+1) / (25x^2+15x+2)] - [(3x-2) / (30x^2+11x+1)]
= [(4x+1) / (5x+1)(5x+2)] - [(3x-2) / (5x+1)(6x+1)]
lcd = (5x+1)(5x+2)(6x+1)
= [(4x+1)(6x+1)/lcd] - [(3x-2)(5x+2)/lcd]
=[24x^2+10x+1 - (15x^2-4x-4)]/lcd
=[9x^2+14x+5]/lcd
=[(9x+5)(x+1)]/[(5x+1)(5x+2)(6x+1)]
================
