Question

1/a+b+x=1/a+1/b+1/x solve step by step and send image pls

Answer 1

the solution is in the image
Hope it will help

Answer 2

1/(a+b+x)=1/a + 1/b + 1/x

1/(a+b+x) -1/x = 1/a + 1/b

x-(a+b+x)/x(a+b+x) = a+b/ ab

-1(a+b) /x(a+b+x) = a+b/ ab

-1(a+b)/(a+b) = x(a+b+x)/ab

-1=x(a+b+x) / ab

-ab= (a+b)x + x2

so, x2 + (a+b)x +ab = 0

now, A = 1, B=(a+b) C= ab..

so, D = B2 - 4AC

  =(a+b)2 - 4ab

  = (a-b)2

so, x = (-B + root D)/2A  and (-B-root D)/2A

  = -a-b+a-b /2*1   and  -a-b-a+b /2*1

  = -2b/2  and -2a /2

so,x = -b or -a...answer,,, :)
