  2. 2. Warm-Up/Test Prep:5 5. (2x - 3)(x + 2)(x - 1) 3. (y - y2 ) - (2y - 2y2 ) 1. The sum of 2 binomials is 5x2 - 6x. if one of the binomials is 3x2 - 2x, what is the other binomial? All Questions are very similar to tomorrow's. 2. 9x6 - 18x4 + 5x2 2x4 4. (2y2 + 3xy - 4) - (- 5x2 + 5xy + 2) =
  3. 3. Binomial Sign Summary (x + 4)(x + 3) Middle Term Last Term positive positive (x - 4)(x + 3) negative negative (x + 4)(x - 3) positive negative (x - 4)(x - 3) negative positive Which term is bigger doesn't matter when both signs are the same, but it does when the signs are different. *In this case, because the negative coefficient is larger than the positive. *See above
  4. 4. Special Products are three types of binomials that occur frequently in algebra. Because of this, you will benefit by memorizing their patterns. It will help a great deal when we start factoring (soon). Here they are: P.S. You'll want to write this down. You should be able to recognize the products both ways. (x2 + 16x + 64) = ( )2x + 8 (4p2 + 16pr + 16r2 ) = ( )22p + 4r
