Solve for nn. Express your answer as an integer or integers or in simplest radical form.

Question

-10+2n^2- -2

Answer 1

To solve for n, we start by simplifying the expression:

-10 + 2n^2 - (-2)
-10 + 2n^2 + 2

Combine like terms:
2n^2 - 8

Set the expression equal to zero:
2n^2 - 8 = 0

Add 8 to both sides:
2n^2 = 8

Divide by 2:
n^2 = 4

Taking the square root of both sides:
n = ±2

Therefore, n = 2 or n = -2.
