1/(x+a)=[2/(x-1)]-[1/(x-a)] solve for x

myininaya (myininaya):

$\frac{1}{x+a}=\frac{2}{x-1}-\frac{1}{x-a}$

OpenStudy (anonymous):

let me know when you get $x=a^2$

myininaya (myininaya):

$(x+a)(x-a)(x-1)\frac{1}{x+a}=(x+a)(x-a)(x-1)\frac{2}{x-1}-(x+a)(x-a)(x-1)\frac{1}{x-a}$

myininaya (myininaya):

$(x-a)(x-1)=(x+a)(x-a)(2)-(x+a)(x-1)$

myininaya (myininaya):

$(x-a)(x-1)=(x+a)(2(x-a)-(x-1))$

myininaya (myininaya):

$(x-a)(x-1)=(x+a)(2x-2a-x+1)$

myininaya (myininaya):

$(x-a)(x-1)=(x+a)(x-2a+1)$

myininaya (myininaya):

$x^2-x-ax+1=x(x-2a+1)+a(x-2a+1)$

myininaya (myininaya):

$x^2-x-ax+1=x^2-2ax+x+ax-2a^2+a$

myininaya (myininaya):

put like terms together

myininaya (myininaya):

move everything to one side

myininaya (myininaya):

well actually the x^2's cancel so don't

OpenStudy (anonymous):

okay I got it from there thank you so much!!!

myininaya (myininaya):

make sure $x \neq -a, x \neq 1, x \neq a$

OpenStudy (anonymous):

ok

myininaya (myininaya):

let me know if you need further assistance :)

OpenStudy (anonymous):

Im lost how you went from (x+a)(2x-2a-x+1) to (x+a) (x-2a+1) where did the 2's and x go to

myininaya (myininaya):

2x-x=x

myininaya (myininaya):

this is was the last step i got to for him $x^2-x-ax+1=x^2-2ax+x+ax-2a^2+a$

myininaya (myininaya):

next step is to: put x terms on one side and everything without x on the other side
