square the length of a side.
We have already seen that 2(x+1) = 2x+2
We were able to do this multiplication by using the
distributive property. We can also use the
distributive property when we are multiplying
polynomials by polynomials.
term in the first set of parentheses through
the second set of parentheses.
1.) (x+2) (x+8)
2.) (x+5) (x-7)
3.) (2x+4) (2x-3)
1.) (x+2) (x+8) = X2+10x+16
2.) (x+5) (x-7) = X2-2x-35
3.) (2x+4) (2x-3) = 4x2+2x-12
(x+1)(x2+2x+3) = X3+2x2+3x+x2+2x+3
