SUMMARY

The discussion centers on the equation (y - a)^2 = p(x - e) and the subsequent transformation to 2ay - a^2 = pe. The participant, Nicole, initially struggled to understand the subtraction step that led to this result. Ultimately, she resolved her confusion by recognizing that she had mistakenly referenced an earlier equation in her calculations. This highlights the importance of tracking all equations in problem-solving.

I'm looking at an example of a problem in my book and one line says

(y - a)^2 = p(x - e)

and then it says by subtracting they get

2ay - a^2 = pe

I'm not seeing what they subtracted to get that...

Please help me!

Nevermind, I figured it out...I was actually subtracting out an equation from earlier in the problem.
