Answer 1

factor out what?

Answer 2

are you sure its 8xy?

Answer 3

Dr. House? your wanted at your question...

Answer 4

\[\large 1*(4y^2 + 16x^2 + 24xz^2 - 8xy + 9z^4 - 12yz^2)\]

Answer 5

:)

Answer 6

that's the expression..no mistakes

Answer 7

see

\[a^2 + b^2 +c^2+2ab+2bc+2ca = (a+b+c)^2\]

In your question
a = 4x
b = -2y
c = 3z

:)

Answer 8

Answer 10

So add and subtract 8xy

Answer 11

hmm i think my teacher mentioned a correction about this -_- i cant recall that was one year ago lol sorry :P

Answer 12

lol

Answer 13

So it should be
\[(4x-2y+3z^2)^2 +8xy\]
