Question 985163
let x, y be the 2 parts 
  x+y=75
  xy =1250
formula: {{{(x-y)^2=(x+y)^2-4xy}}}
     {{{(x-y)^2=(75)^2-4*1250}}}
    {{{(x-y)^2=5625-5000}}}
{{{(x-y)^2=625}}}
  {{{x-y =sqrt(625)}}}
    x-y =25
   x+y= 75
   x-y=25
  add both the equations
   2x=100
  x=50
 y=25
Result : x=50, y=25
  75 is divided into 50 and 25
