9.3 Find Special Products Of Polynomials

My Examples: (x + 5) ^2 = x2 + 10x + 25 (2x - 3)^2 = 4x^2 - 12x +9

(3x + 4)^2 = (3x)^2 + 2(3x)(4) +(4)^2  = 9x^2 + 24x + 16

Main ideas: multiply polynomials now you will use special product pattern to multiply polynomials. You do this so you can make a scientific prediction (pg569)
problem 1: (x+3)^2 F-first (X+3)(X+3) O-outside x^2+3x+3x+9 I - Inside X^2+6X+9 L - Last

problem 2: (6x+5)^2 solve

**(a+b)^2=a^2+2ab+b^2 and (a** +b)
Now find the product of the square of the binomial
