How are we going to factor this??**Factoring Steps for Trial and Error**– 6x2 – x + 2 Wow! How are we going to factor this?? Well, let’s try another method and see if that will help with this problem. We can try Factoring by Grouping.**Factoring Steps for Grouping**x2 + 5x + 6**Factoring Steps for Grouping**x2 + 5x + 6 x2 + 2x + 3x + 6**Factoring Steps for Grouping**x2 + 5x + 6 x2 + 2x + 3x + 6 x2 + 2x + 3x + 6**Factoring Steps for Grouping**x2 + 5x + 6 x2 + 2x + 3x + 6 x2 + 2x + 3x + 6 x(x + 2) +3(x + 2)**Factoring Steps for Grouping**x2 + 5x + 6 x2 + 2x + 3x + 6 x2 + 2x + 3x + 6 x(x + 2) +3(x + 2) (x + 2) (x + 3)**Factoring Steps for Grouping**3x2 – 4x – 4**Factoring Steps for Grouping**3x2 – 4x – 4 3x2 – 6x + 2x – 4**Factoring Steps for Grouping**3x2 – 4x – 4 3x2 – 6x + 2x – 4 3x2 – 6x + 2x – 4**Factoring Steps for Grouping**3x2 – 4x – 4 3x2 – 6x + 2x – 4 3x2 – 6x + 2x – 4 3x(x – 2) 2(x – 2)**Factoring Steps for Grouping**3x2 – 4x – 4 3x2 – 6x + 2x – 4 3x2 – 6x + 2x – 4 3x(x – 2) + 2(x – 2) (x – 2) (3x + 2)**Factoring Steps for Grouping**3x2 – 4x – 4 3x2 – 6x + 2x – 4 3x2 – 6x + 2x – 4 3x(x – 2) 2(x – 2) (x – 2) (3x + 2) Or it can be factored this way . . .**Factoring Steps for Grouping**3x2 – 4x – 4
