Answer:
x = 1/25
Step-by-step explanation:
Define x:
Let the number be x
Form the equation:
x + √x = 6/25
Define y:
Let y be √x
Rewrite equation:
y² + y = 6/25
Solve y:
y² + y = 6/25
25y² + 25y = 6
25y² + 25y - 6 = 0
(5y - 1) (5y + 6) = 0
y = 1/5 or y = -6/5 (rejected)
Solve x:
y = √x
1/5 = √x
√x = 1/5
x = (1/5)²
x = 1/25
Answer: x = 1/25
