11 How do we get from (x+3)(x+1) to ? We have already seen that 2(x+1) = 2x+2We were able to do this multiplication by using thedistributive property. We can also use thedistributive property when we are multiplyingpolynomials by polynomials.
12 We need to remember to distribute each term in the first set of parentheses throughthe second set of parentheses.Example:(X+3)(x+1)=(x)(x)+(x)(1)+(3)(x)+(3)((1)
13 Let’s work a few of these. 1.) (x+2) (x+8)2.) (x+5) (x-7)3.) (2x+4) (2x-3)
14 Check your answers. 1.) (x+2) (x+8) = X2+10x+16
15 (x+1)(x2+2x+3) = X3+2x2+3x+x2+2x+3 By learning to use the distributive property, you will be able to multiply any type of polynomials.Example: (x+1)(x2+2x+3)(x+1)(x2+2x+3) = X3+2x2+3x+x2+2x+3
