Expanding and Factoring

Expand and simplify:
(m+11)²

• m²+22m+121

• m²+11m+121

• m²+11m +11

• m²+22m +11

Factor Completely:  3n² - 15n + 18

• (n - 2)(n - 3)

• 3(n + 2)(n + 3)

• (3n - 9)(n - 2)

• 3(n - 3)(n - 2)

Factor Completely:  15t² - 27t - 6

• 3(5t +1)(t - 2)

• (3t - 6)(5t + 1)

• 3(5t - 1)(t + 2)

• (15t + 6)(1t - 6)

Find the Product (expand).
(2n + 3)(2n + 1)

• 4n² + 8n + 3

• 4n² - 8n - 3

• 4n² + 8n - 3

• 4n² - 8n + 3

If a = 4x and b = 5, write a SUM of Cubes Problem that would need to then be factored.
