Today's soundtrack is Meshuggah: Chaosphere, perhaps the best album from the grandfathers of djent. Their music video for the song "New Millenium Cyanide Christ" is hilarious.
This afternoon, I'm working on the assignment portion of the lesson I did on the quadratic function in vertex form. Parts one and two are here and here.
Through a bit of trial and error, I figured out that if I substitute 0 for y in the vertex form, I can solve the equation, turning it into standard (or expanded) form, and then I can use the quadratic formula to find the x intercept(s).
