The Quadratic Formula
Use the Formula
There are actually quite a few ways to solve quadratic equations (and you'll learn at least three in your college algebra classes), but for most GED® students, just learning the quadratic formula is enough. It always works, plus the formula is on the GED® formula sheet.
