Then factor the expression.
14y^2+7y-21
----
GCF: 7
---
= 7(2y^2 + y - 3)
----
= 7(2y^2 + 3y-2y -3)
---
= 7(y(2y+3)-(2y+3))
----
= 7(2y+3)(y-1)

Find the GCF of the expression. Then factor the expression.
14y^2+7y-21
-----------------
GCF means a factor that is common to 2 or more expressions.
You show only one expression, a trinomial.
-----
You can say find the GCF of 14y^2, 7y & -21, but not the GCF of a single expression.
------
It can be factored:

-------
7 is not a GCF, it's a factor of the trinomial.
