Help on evaluating expression

Postby monsoon » Wed May 09, 2012 5:56 pm

Evaluate and simplify y=2x+1/x+1 if x=1+h

this is what i got so far,

2(1+h)+1/(1+h)+1 ---> 2+h+1/(1+h)+1

and i'm stuck there. the way i did it doesn't seem right please help!

then I don't get how you got the step you showed :confused:
plug the "1+h" in for all the "x"s

then please SHOW your steps
like, how did you get 2(1+h)=(2)(1)+(2)(h) equal to 2+h not 2+2h?
thnx
