## Homework Statement

Write F(x)= x

^{2}-5|x| as a piecewise function

## Homework Equations

## The Attempt at a Solution

I was writting it out and came to

Fx= x

^{2}-5(x) and x

^{2}-5(-x)

but my book says that it comes out to be

x

^{2}-5

x

^{2}-5(-x)

I imagine there is a very simple reason why the x in the first one disappears but i would love an explanation, thank you!
