7 Multiplying Polynomials Binomial Theorem and Pascals Triangle

8 1n = 0 1 1n = n = n = 3 ???n = 4

9 Binomial Theorem 1n = 0 1 1n = n = n = 3 (a+b) 0 = 1 (a+b) 1 = 1a + 1b (a+b) 2 = 1a 2 + 2ab + 1b 2 (a+b) 3 = 1a 3 + 3a 2 b + 3ab 2 + 1b 3

10 Binomial Theorem 1n = 0 1 1n = n = n = 3 Use the binomial theorem to write out (x + 3) 2.

11 Binomial Theorem 1n = 0 1 1n = n = n = 3 Use the binomial theorem to write out (x + 3) 3.

12 Binomial Theorem 1n = 0 1 1n = n = n = 3 Try (x + 2) 4.

13 Application x + 2 Find an expression for the area of the base and then, the volume of the box: A = x 2 + 4x + 4 V = x 3 + 6x x + 8 x + 2
