Question

What is the solution of this equation?

-1/2 n2 + 18 = 0


Please help

Answer 1

n= -6 or 6

Explanation:

`-1/2n^(2)+18=0`

first subtract 18 from both sides

now we have

`-1/2n^(2)=-18`

next multiply both sides by 2

now we have

`-1 n^(2) =-36`

next multiply both sides by -1

now we have

`n^(2)=36`

now square root both sides

`n=\sqrt 36`

n=±6

Answer 2

Explanation:

To solve the equation:

-1/2 n^2 + 18 = 0

We can start by isolating the variable term by subtracting 18 from both sides of the equation:

-1/2 n^2 = -18

Then, we can multiply both sides by -2 to eliminate the fraction:

n^2 = 36

Taking the square root of both sides, we get:

n = ±6

Therefore, the solution to the equation -1/2 n^2 + 18 = 0 is n = ±6.
