Solving 3x/(x²-1)=x/(x+1)-4

[aisha]

Another solve for x I GOT IT THIS TIME just check please

can someone please check my answer? The question was (3x)/(x^2-1)=[(x)/(x+1)]-4


my answer x=2/3 , x=-2

Both your solutions seem to be perfectly right.

OH I NEEDED TO STATE THE RESTRICTIONS for this question if there were any but I don't know what step to get the restrictions from, anyone have any ideas?

 

[Parth Dave]

The restriction would be any value of x that you can put into the original equation to make the solution undefined. For example, if you have an equation:
1/x = 6,

x cannot equal zero or the operation is undefined. What would that make the restrictions in your case?

 

[aisha]

are the restrictions x cannot = 1 or -1? or are there more?

 

[mattmns]

Yes, 1 and -1, that's what I see
