Factoring by Grouping Practice

Factor 2x² + 3x - 9.

Factor 3x² + 8x + 4.

Factor 2x² + 11x + 5.

Factor 6x² + 5x - 6.

When do we factor by grouping?

• all the time

• when there are 4 or more terms

• when there are 3 terms

• when it looks hard

Which Factoring Method should you use for:
8n³ + n² +48n +6

• GCF

• DOTS

• Grouping

• TRI

Factor by grouping:
5n³ - 10n² + 3n-6

• (5n²+3)(n-2)

• (5n²-3)(n-2)

• (5n³+3)(n-2)

• 10n(n²-6)

30x³+15x²-18x-9 hint: GCF then Factor by Grouping

• (5x²-3)(6x+1)

• (5x²-3)(6x+3)

• 3(5x²+3)(2x-1)

• 3(5x²-3)(2x+1)

Factor:
56a³-8a

• 8a²(56a³-8a)

• 8a(7a²-1)

• 8a(7a³-a)

• 8a²(35a²-a)

Factor
10x² + 15x-5

• 25(10x³+45x-15)

• 5(2x³ + 3x²-x)

• x(10x³+15x-5)

• 5(2x²+3x-1)
