Factoring Polynomials Box Method

36m² - 9
(Check for a GCF)

• (6m + 3)(6m - 3)

• 9(4m² - 1)

• 9(2m - 1)(2m + 1)

• Not Factorable

Factor
k²+7x+10

• (k+2)(k+5)

• (k-2)(k-5)

• (k+10)(k+4)

• (k+2)(k-5)

Find the error and correct it. You should mark two answers

• The greatest common factor is not 5x. It is 15x

• When factoring the polynomial, there should be three terms inside the parenthesis.

• It is not in standard form

32n² - 50
(Check for a GCF)

• (16n - 25)(16n + 25)

• 2(8n - 25)(8n + 25)

• 2(4n + 5)(4n - 5)

• Not Factorable

factor x² -16x + 48

• (x - 12)(x - 4)

• (x + 12)(x - 4)

• (x + 6)(x - 8)

• PRIME

b² + 2b + 80

• (b - 8)(b + 10)

• (b - 8)(b - 10)

• (b + 8)(b + 10)

6r² - 84r + 288

• 6(r - 6)(r - 6)

• 6(r - 8)(r - 6)

• (r + 7)(r + 5)

r² - 14r + 48

• (r + 6 )(r + 1)

• (r - 6)(r + 8)

• (r - 6)(r - 8)

x² + 8x + 12

• (x - 2)(x + 6)

• (x + 2)(x + 6)

• (x - 2)(x - 6)

What is the name of the method that you need to use when checking your factored polynomial?

• box method

• FOIL method

• no checking necessary
