let the divided part of 750 is x and y
according to the question
xy = 750
and x+y = -55 ............1
formula (a+b)²-(a-b)² = 4ab
(x+y)² -(x-y)² = 4xy
-55² -(x-y)² = 4×750
3025 - (x-y)²= 3000
(x-y)² = 3025-3000
(x-y)² = 25
x-y = 5 ...........2
form eq1 and eq2
2x = -50
x= -25
put x for y
x+y = -55
-25 +y = -55
y= -55 +25
y= -30
hence the no are x= -25 and y= -30
