3n^2 - 75 = 0 please help me solve?

Question

please express solution in simplest radical form.

Answer 1

3(n^2 - 25) = 0
n^2 - 25 = 0
(n - 5)(n + 5) = 0

n = 5, n = -5

Answer 2

Hey there!

Here's the answer.

3n^2-75=0 --> Write the problem.
3n^2=75 --> Add 75 on both sides of the equation.
n^2=25 --> Divide 3 on both sides of the equation.
n=±5 Take the square root on both sides of the equation.

So the answer is n=±5.

Hope it helps!

Answer 3

ok: 3n^2 = 75, so n^2 = 25, and n = +/-5

Answer 4

3 (n ² - 25) = 0
3 (n - 5) (n + 5) = 0
n = 5 , n = - 5
