8/(y^2-64)- (y-5)/(2y^2-15y-8)
--------
Factor:
[8/(y-8)(y+8)] - [(y-5)/(2y+1)(y-8)]
---
lcd = (y-8)(y+8)(2y+1)
---
Rewrite each fraction with the lcd as its denominator:
[8(2y+1)/lcd] - [(y-5)(y+8)/lcd]
---
Combine the numerators over the lcd:
[16y+8 - (y^2+3y-40)]/lcd
---
[16y + 8 - y^2 -3y + 40]/lcd
----
-[y^2 - 13y - 48]/lcd
Factor:
-[(y-16)(y+3)]/lcd
=======================
Cheers,
