Question

1/x+1/(x+2)=1/3

Answer 1

What are you having trouble with?

Answer 2

solving quadratics and finding the descriminant

Answer 3

I don't know wr to start

Answer 4

Start by combining the 1/x and the 1/(x+2)

Answer 5

Can you do that?

Answer 6

do i set both denominators as (x+2)?

Answer 7

As x(x+2). You can't set the first denominator as x+2 because nothing you multiply it by will give you that.

Answer 8

oh I see thanks

Answer 9

this might be wrong but would you get 2/x(x+2)? or 2x/x(x+2)

Answer 10

Just treat it like a fraction.
\[\frac{ 1 }{ x }*\frac{ x+2 }{ x+2 } + \frac{ 1 }{ x+2 }*\frac{ x }{ x }\]
\[\frac{ x+2 }{ x(x+2)}+\frac{ x }{ x(x+2) }\]
\[\frac{ 2x+2 }{ x(x+2) }\]

Answer 11

thanks
