Question 3
3.
Which option results from factoring out the GCF from among the terms of the polynomial 16y^{2}+56y+49?
y^{2}(16+56y^{-1}+49y^{-2})
8(2y^{2}+7y+6)
7(\frac{16}{7}y^{2}+8y+7)
y^{2}(16+\frac{56}{y}+\frac{49}{y^{2}})
The polynomial is already fully factored.

(w)y^{3}+(x^{2}z^{2})y^{2}+(x^{2}w^{2}-z^{2})y
x^{2}y^{2}z^{2}+x^{2}w^{2}y+y^{3}w-yz^{2}
