Question

he sum of a number and its positive square root is 6/25. Find the number
​

Answer 1

Step-by-step explanation:

Let the number be n^2. So

n^2 + n = 6/25, or

25 n^2 + 25 n = 6, or

25 n^2 + 25 n - 6 = 0

The product of 25 and -6 = -150. Its factors are +30 and -5. So we re-write the equation as

25 n^2 + 30 n - 5 n - 6 = 0, or

5n (5n +6) - 1*(5n + 6) = 0, or

(5n - 1)(5n +6) = 0

Therefore n = 1/5 or -6/5.
