SUMMARY

The discussion centers on simplifying the expression \(\frac{4h}{x + h - x}\). The key takeaway is that the expression simplifies directly to \(\frac{4h}{h}\), which further reduces to 4, provided that \(h \neq 0\). Participants emphasize the importance of recognizing that \(x + h - x\) simplifies to \(h\), which is crucial for correctly evaluating the expression.

Part f. is the only expression I am unsure of what steps to take to get the correct answer.

Would anyone be willing to give me an idea?

Why did you stop at \frac{4h}{x+ h- x}? You are aware that x+ h- x= h, aren't you?
