Solve for x: 2x² − 8x + 6 = 0

1Take out the common factor2(x² − 4x + 3) = 0
2Factor the quadratic2(x − 1)(x − 3) = 0
3Set each factor to zerox − 1 = 0 or x − 3 = 0

Answerx = 1 or x = 3

Glucose comes apart in three stages: glycolysis, the Krebs cycle, then the electron transport chain.

The first two stages hand over only 4 ATP - the rest is made at the membrane.

Oxygen's whole job is to accept the last electron and keep the chain moving.

Honestly a lifesaver at university. I drop in a lecture and Ozard summarizes it and makes flashcards in seconds - so I actually learn what I wrote down.

Really useful both for studying for a test and prepping for a quiz. I highly recommend it.

Carolina B. · Student

I upload my readings the night before and quiz myself on the way to class. My grades genuinely went up this semester.

Daniel K. · Student

It pulls answers straight from my own notes instead of making things up. That's the part I trust the most.

Everything from my semester lives in one place now - PDFs, lecture videos, my messy notes. I just ask.
