How would you simplify

(-x^2+2xh+h^2-2x-2h-2x^2+4x)/h ?

The expression you posted doesn't look right.

Are you looking for the simplification of
((x+h)²-2(x+h) - x² +2x)/h ?

Oh! I think I made a mistake in writing out the equation! thanks for pointing it out. I know what to do now thank you!

To simplify the expression, we need to combine like terms and simplify any fractions. Let's break down the steps:

1. Combine like terms in the numerator:
(-x^2 - 2x^2) + (2x - 2x) + (h^2 - 2h) = -3x^2 + h^2 - 2h

2. Now, let's rewrite the simplified expression:
(-3x^2 + h^2 - 2h) / h

3. Divide each term in the numerator by h:
-3x^2/h + h^2/h - 2h/h

4. Simplify each term:
-3x^2/h + h - 2

Therefore, the simplified expression is:
(-3x^2/h + h - 2)
