Question

What is the first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k?
16 must be factored from 18x + 14
x must be factored from 6x2 + 18x
6 must be factored from 6x2 + 14
6 must be factored from 6x2 + 18x

Answer 1

this is kind of hard to explain w/o giving too much away but try following the example given here:

to see where the first factoring happens
