    I'll assume the x should be c or a, doesn't matter Do you know to multiply top and bottom by (sqrt 2c-a) +a

    and once you do you have (2c-a)-a on top (a-c)(sqrt (2c-a) + a on bottom now factor out -2 on top and you have -2(a-c) -a and you can cancel out the (a-c)

    and now you are at the point where it matters if your x is supposed to be a or c
