Factorising polynomials

• GCF

• Perfect Squares

• X – Factor

  (Simple)

• X – Factor and Grouping or divide by a value

Factoring out the GCF

• I know how to factor by GCF

• I don't remember how to factor by the GCF

• I practically guess every question

• What is this?

Factor:

2n²-8n³

• 2n²(n-4n²)

• -2n²(4n-1)

• 2n³(10-8n²)

• 3n(1-4n)

Factor:

56a³-8a

• 8a²(56a³-8a)

• 8a(7a²-1)

• 8a(7a³-a)

• 8a²(35a²-a)

Find the LCM:

8x⁵y⁴ and 14x⁶y²

• 56x⁶y⁴

• 56x⁵y²

• 2x⁵y²

• 2x⁶y⁴

Find the prime factorization of 108

• 2³ * 3²

• 2² • 3³

• 2⁵ • 3

• 2 • 3 • 7 • 11

Factor the GCF:

36m³n - 6n⁴

• 6n² (6m - n)

• 6n² (6m³ - 1)

• 6n (6mn - 1)

• 6n (6m³ - n³)

Factor by pulling out the GCF

16xy - 24y

• 4y (4x - 6)

• 8y (2xy - 3y)

• 8y (2x - 3)

• 2xy (8 - 12y)

given f + 1 / f²-3f ,what is the GCF of the denominator?

• f

• -f

• 3

• -3
