Which zero pair could be add into the function f(x)=x^2+12x+6 so that the function can be written in vertex form

We need a perfect square, and we start with

This means that the binomial begins with , and is the double product of and the number we're looking for. So, that number is . Since

we need to add (and subtract it to leave the expression untouched. So, we have

just needed some points but try socratic

6mm^3 or .6cm^3

factor trees are nice.
