Example 1Factor.x2 − 10x + 16
To factor a trinomial:1. GCF?2. Put in standard form.3. Is a = 1?4. Draw your parentheses. (x )(x )5. Puzzle: *c for ceiling, b for basement!6. Find the two magic numbers. 7. Fill in your parentheses. *if a magic number
is negative, write as a subtraction inside ( )*8. FOIL/BOX/DISTRIBUTE to check your
answer!
