Question

x-y=15 ,, root x - root y =1 then x=?

I want traditional way of solving... not option test or possibility ​

Answer 1

Answer:

Given x-y=15 and rootx-rooty=1 then x=? Sol- rootx-rooty=1 square on both sides then x+y-2rootxy=1 then x+y=1+2rootxy now add equation 1 and 2 x-y=15 and x+y=1+2rootxy then we get 2x=16+2rootxy then x=8+rootxy
