Simplify 2/x + 2/x+1 - 2/x+2. Show the restrictions. Can someone show me how to solve this please?

Question

anonymous · Answer

$$2/x+2/x+1-2/x+2$$

jhonyy9 · Answer

restrictions will be for x values for what the denominators are zero

jhonyy9 · Answer

now can you check it what are these values ?

jhonyy9 · Answer

x=0
x+1=0 so than x=-1 
and the 3rd what will be ?

anonymous · Answer

-2?

jhonyy9 · Answer

yes right

anonymous · Answer

How do i simplify the problem?

jhonyy9 · Answer

can you calcule the common denominator ?

anonymous · Answer

No I'm not sure how to do that.

jhonyy9 · Answer

so than you will can adding these

jhonyy9 · Answer

so like denominators there are

x
x+1
x+2

so now you see that x+2 not can divide by x or x+1 and x+1 is the same not can divide by x 

so in this case the common denomintor we will get if we make the product of x and x+1 and x+2 so like x(x+1)(x+2)

jhonyy9 · Answer

ok ?

jhonyy9 · Answer

so than now for we can adding these terms after we know the common denominator we need multiplie the first numerator by (x+1)(x+2) and the second numerator by x(x+2) and the 3rd numerator by x(x+1) 

- can you calcule it ?

anonymous · Answer

Yes, hold on.

Is the first fraction 2x^2+6x+4/x^3+3x^2+2x?

anonymous · Answer

$$2x^2+6x+4/x^3+3x^2+2x$$
