1. Use FOIL:  Front   Outer  Inner  Last


Multiplying Polynomials
 

Use the Distributive Property (works for any multiplication)
 Ex) Simplify 3(5z – 6) =
 
 
Ex) Simplify 2x2y(-3x + 2y – 4) =
 
 
 
 Ex) Simplify (b2 + 2b – 1) – 3b(b + 5) =
 
 
 
 
 Ex) Simplify (a + 1)(a2 + 2a + 1) =
 
 
 
 
 
Use FOIL:  Front    Outer    Inner    Last
 (only good for multiplying binomials)
 
 Ex) Simplify (z + 3)(z + 4)
   Using Distributive Property        Using FOIL
 
 
 
 
 
 
 Ex) Simplify (x + 1)(x + 3)
 
 
 
 
 
 
 Ex) Simplify (3w + 7)(2w – 5)
 
 
 
 
 
 
TRY – Simplify
1. 6(4a – 2)          2. (8v – 3)(-5v)
 
 
3. (b + 6)(b – 1)        4. –5p2(p2 + 2p + 1)
 
 
 
5. (2t – 5)(5t – 2)        6. (2d +4)2
 
 
 
 
7. 8w – 5(2w + 7)        8. (2n – 7)(n2 – n + 3)
