Factorization by Grouping

Factor by grouping:
3x³-x²+6x-2

• (x²+2)(3x+1)

•  (x²+2)(3x-1)

• (3x³+6x)(x²-2)

• none of the aboe

Factor by grouping:
5n³-10n²+3n-6

• (5n²+3)(n-2)

• (5n²-3)(n-2)

• (5n³+3)(n-2)

• 10n(n²-6)

6xy - 8x + 15y - 20

• (3y + 4)(2x - 5)

• (3y - 4)(2x + 5)

• (2y - 4)(3x + 5)

• (2y + 5)(2y - 4)

4b² - 12b + 2b - 6

• (b - 3)(4b + 2)

• 2(2b + 1)(b - 3)

• (4b + 3)(b - 2)

• (4b - 3)(b + 2)

When factoring, the first thing you look for is ​ (a)   . If there are two terms, try to factor by using ​ (b)   If there are three terms, try to factor by using ​ (c)   If there are four terms, try to factor by using ​ (d)  

• GCF

• DOTS

• Trinomial a*c & b

• Grouping (Chop it)

Factor Completely: 14p²-24p-8

• (5p+3)(p-4)

• (3p-2)(p+10)

• 2(7p-2)(p+2)

• 2(7p+2)(p-2)
