explain how the values of a and c in ax^2+bx+c help you determine whether you can use a perfect square trinomial factoring pattern

Step-by-step explanation:

So essentially, it actually doesn't just rely on the a and c values, it also has a little to do with the b value.

If you divide the c term by the a term, and the number is a perfect square, and moreover, if you divide the b term by the a term, then divide it by 2, and then square it, if it equals the c term, then you have a perfect square.

For example, 2x^2 + 12x + 18

if you divide 18/2, you get 9 ( a perfect square)

if you then divide the b term (12) by the a term (2), you get 6, which if you divide by 2, you get 3, and then if you square, you get 9, try this pattern, and if it works, then the expression can be factored using a perfect square trinomial factoring pattern.
