Question

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

Answer 1

The GCF for a polynomial is the largest monomial that divides (is a factor of) each term of the polynomial. Identify the GCF of the polynomial. Divide the GCF out of every term of the polynomial. Use that process for a, b, and c in ax^2 + bx + c.

Answer 2

One way is to reverse logic it
(3x+4)^2=9x^2+24x+4


ok so
if 2(√a)(√c)=b, then you have a perfect square trinomial
