Question 117849: Hello out there,I need some help with some tough problems,the first one is,Find the LCM for x^2+3x+2 and x^2+5x+6.The next one is,Find the LCD for 3/w and 4/w^2.The third one is,Simplify:3/x+x+3/y.And the last one is,Simplify:4y/y+2+-y/y+2.Thanks to whoever can help.

You can put this solution on YOUR website! Hello out there,I need some help with some tough problems,
the first one is,Find the LCM for x^2+3x+2 and x^2+5x+6.
Ans: (x+2)(x+1)(x+3)
--------------------------------------
The next one is,Find the LCD for 3/w and 4/w^2.
Ans: w^2
---------------------------------------
The third one is,Simplify:(3/x) + (x+3)/y
(3y + x(x+2))/xy
===============
And the last one is,
Simplify:(4y)/(y+2) + (-y)/(y+2)
= [4y -y]/(y+2)
= 3y/(y+2)
====================
Cheers,
Stan H.
