1. Factor Review
Algebra B

2. How many Terms? Two Factor out GCF
Difference of Squares: Both terms square separated by minus

3. How many Terms? Three First factor out GCF if there is one
Check if you can factor more
Remember: Multiply to last term add to middle.
ax2+bx+c=( + )( + ) ax2-bx+c = ( - )( - ) ax2 bx-c = ( + )( - )
Use Guess and check or Split the middle term

4. How many Terms?
Three
Guess and check

5. How many Terms? Three Split the middle term
Multiply a with c (6)(-20)=-120
Find 2 numbers that multiply to answer and add to b -15 and 8
Now split the middle
Next factor by grouping

6. How many Terms? Four Factor by grouping
Make sure the two groups are separated by a +
Factor the GCF from each group
Factor the common binomial
