Create a perfect square trinomial that can be factored using special patterns. Factor the trinomial and show all work for full credit.

Answer 1

let's start with a simple binomial of degree 2,. say x²+18x. use complete the square method to get

x²+18x=0
x²+18x+81 =81
(x+9)²=81
x+9=±9
x=-9±9
x=0 or -18
