Today's soundtrack is Evanescence: The Open Door.
This evening, I'm continuing to work on my assignment from the Quadratic Formula lesson. The first two parts of my homework can be found here and here.
It was a lot of work, but I've finally finished this section. One problem that I ran into was on a question asking me to convert radicals to a quadratic equation before solving. I made a mistake in squaring, forgetting to isolate the radical before applying the square. Once I got that sorted, I made slow but steady progress through the rest of the questions.
