Question

Solve for f. h = f² + 2g

Answer 1

f^2=h-2g
f=√h-2g
hope it helps

Answer 2

Answer:

$f=\sqrt{h-2g}\text{ or }f=-\sqrt{h-2g}$.

Step-by-step 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.

$f=\pm\sqrt{h-2g}$

Therefore, the values of f are $f=\sqrt{h-2g}\text{ or }f=-\sqrt{h-2g}$.
