Question

if x=4ab/a+b then the value of (x+2a/x-2a) +(x+2b/x-2b)

Answer 1

`````Take a cross multiplaction `````
`
= [x+2a] [x-2b] + [x-2a] [x+2b]   /  [x-2a] [x-2a] 
= [x^-2bx+2ax-4ab ] + [x^+2bx-2ax-4ab ]   /  [x^-2bx-2ax+4ab]
= take a same variable numbers,
= [x^+x^-2bx+2bx+2ax-2ax-4ab-4ab]  /  {x-2a} {x-2b}
= [2x^-8ab ] / [x-2a] [x-2b]

Ans. = {2x^-8ab} / {x-2a} {x-2b}
