Polynomials and Factoring Test (S)

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

• GCF

• Difference of Squares

• Quadratic Trinomial

• Grouping

• 15ab(a + 2)

• 15ab(a - 2)

• 5ab(3a - 10)

• 5ab(3a + 10)

How would you factor?

4x² - 9

• GCF

• Difference of Perfect Squares

• Quadratic Trinomial

• Grouping

Factor 4x² - 9

• (x - 15)(x - 3)

• (x + 15)(x + 3)

• (x - 15)(x + 3)

• (x + 15)(x - 3)

• GCF

• Difference of Squares

• Quadratic Trinomial

• Grouping

Simplify the expression.
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

• -8n² - 8n + 3 
• -7n² - 8n + 3 
• -6n² - 8n + 3
• -7n² - 4n + 3

Rewrite in Standard Form:

7x - 125 - 6x⁴ + 14x²

• 125 + 7x - 14x² +6x⁴

• 6x⁴  -14x² - 7x +125

• 125 + 14x² + 7x  - 6x⁴

• -6x⁴+ 14x² + 7x - 125

What is the perimeter of this triangle?

• 8xy + 3

• 5x + y + 3

• 5x + 4y + 3

• 6x + 3y + 3
