Factoring
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Factoring rewrites a polynomial as a product; it is multiplication run backward, and multiplying back is the check.
Show
x² + 8x + 15 factors as (x + 3)(x + 5); multiply the factors back and the original returns.
Watch for
An answer that fails the multiply-back check is not a factoring.

- Nothing — this is a starting point.
Unlocks
