I know this should be in algebra, but im confused where to start. I honestly havent done any of this in years. Originally Posted by Chris L T521 Where are you stuck? Take it from here. Its just expanding and simplifying from here on out. --Chris

See if you can finish simplifying this expression. The remaining terms in the numerator should have at least one h. --Chris
