#### Storyboard Text

• My teacher told us to find another way to factor 3x3 +13x+4 but there is no GCF!
• I heard math is difficult, what's up?
• I'm not sure how the school cop would feel about that﻿
• There is one more way to factor that...it's called the...illegal move.
• So 3 times 4 to get x2﻿+13x+12, then what?
• It's not actually illegal...I hope anyway. Here: since there's no GCF, first you multiply coefficient A by C﻿
• So after all of that, the factors are (x+12/4) or (x+3)(x+1/3)? That doesn't multiply into my original expression!
• Then you use the diamond method to get factors (x+12)(x+1) ﻿and use the coefficient as the denominator for both and finally simplify
• So the final factors are (3x+1)(x+4) which multiplies to my expression! The illegal move makes sense now
• Ah, when you simplify ﻿a fraction <1, you put the coefficient in front of x in the factors meaning it would be 3x+1
• Did I hear something about an illegal move?!﻿
• Uh oh...﻿
