Keeping Every Factor
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
An equation with the variable on both sides of a product is solved by factoring, never by dividing the variable away; every factor holds a solution.
Show
x² = 5x moves to x² − 5x = 0 and factors: x(x − 5) = 0, so x = 0 or x = 5. Both check.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
