Question

Samuel and Ariana are competing in a speed round for an open position on the math team. To win the spot , each student must factor the same polynomial expression , 12xy * z ^ 2 + 16x ^ 2 * y ^ 2 * z - 32x ^ 2 * y * z , by finding the GCF .

Answer 1

He factor 2 instead of 4

Explanation:

4xyz (3z + 4xy - 8x)

Answer 2

I'm not completely sure but...I believe Samuel factored out a 2 when he should have factored out a 4.

Explanation:

First:

You have to factor the equation...

12xyz^2+(162)(y2)z−32x^2yz

=−32x^2yz+12xyz^2+256y^2z

=4yz(−8x^2+3xz+64y)
