  1. Factoring Review and Factoring Trinomials

  2. Find the factors of the term and identify as prime or composite. 18:

  3. Write the prime factorization of the term -70a2

  4. Find the GCF of the terms 32a 24ab

  5. Use distributive property to factor the terms. If the term cannot be factored, write prime. 15x – 25x2

  6. Factor the trinomial. If the term cannot be factored, write prime. X2 – 9x + 8

  7. Solve for each trinomial. (2x + 5)(x – 9) = 0 4y2 – 6y = 0

  8. Rules for factoring trinomials • Make sure the problem is in descending order. • Use distributive property to pull out any common term from every part and write that GCF in front of all the parentheses. • Find the pairs that multiply to make the first and third terms. • Fill factors into the two parentheses so that the cross multiplication will make the middle term. • Don’t forget to check your signs using the pattern you have in your notes. You can also check your work by multiplying back the problem to see if you get what you started with.

  9. Factor each trinomial. If the trinomial cannot be factored, write prime. 7x2 – 16x + 4 5t2 + 17t – 12

  10. 6p2 – 20p + 16 14a2 – 15a + 4

  11. 6x2 + x – 12 8n2– 36n + 40

  12. 16a2 =81 6b3-24b2+24b = 0
