Multiply (3b – 2)(2b – 3)
Multiply (4t + 3)(4t + 3)

2. 10.3 Special Products of Polynomials

3. Notes
Sum and difference pattern (a+b)(a-b) = a2 – b2 Ex: (5t – 2)(5t + 2) = 25t2 - 4
Square of binomial pattern (a+b)2 = a2 + 2ab + b2 Ex: (3n + 4)2 9n2 + 24n + 16 (a-b)2 = a2 – 2ab + b2 Ex: (2x – 7y)2 4x2 – 28xy +49y2

4. Write the product of the sum and difference - T

5. Write the product of the sum and difference - sT
(x + 9)(x - 9) (7 + c)(7 - c)

6. Write the square of the binomial as a trinomial - t
(x + 4)2 (2t + 3)2
(x – 5)2
(3y – 5)2

7. Write the square of the binomial as a trinomial - st
