Question

Solve for f. h = f² + 2g

Answer 1

f^2=h-2g
f=√h-2g
hope it helps

Answer 2

`f=√(h-2g)\text{ or }f=-√(h-2g)`.

Explanation:

We have been given an equation
`h=f^2+2g`. We are asked to solve for f.

First of all, we will subtract
`2g` from both sides of our equation.

`h-2g=f^2+2g-2g`

`h-2g=f^2`

`f^2=h-2g`

Now, we will take square root of both sides of our equation.

`f=\pm√(h-2g)`

Therefore, the values of f are
`f=√(h-2g)\text{ or }f=-√(h-2g)`.
