Question

7n² + 2407n - 61800 = 0

Answer 1

Hello Friend,
Here's the solution.



7n² + 2407n - 61800 = 0
So, 7n² - 168n + 2575n - 61800 = 0
So, 7n(n - 24) + 2575(n - 24) = 0
So, (n - 24)(7n + 2575) = 0

So, n - 24 = 0 or 7n + 2575 = 0
So, n = 24 or n = -2575/7


Hope it helps.

Answer 2

7n² + 2407n - 61800 = 0
⇒7n² - 168n + 2575n - 61800 = 0
⇒7n(n - 24) + 2575(n - 24) = 0
⇒(n - 24)(7n + 2575) = 0

⇒n - 24 = 0 or 7n + 2575 = 0
∴n = 24 or n = -2575/7
