Quadratic Equations
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A quadratic equation can be written in standard form ax² + bx + c = 0 with a nonzero; the defining feature is degree 2.
Show
x² − x − 6 = 0 qualifies; 3x + 7 = 19 stays linear.
Watch for
Standard form first; every method reads from there.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
