Prime

Answer 1

Choices are all wrong :| Are you sure it's the right question?

because
\(3x^2 + 12x + 7 \\
3(x^2+4x)+7 \\
3x(x+2)+7\)

Answer 2

I was wondering the same thing, I couldn't figure it out. Those are the correct choices and numbers, but I was thinking that it could be prime, but that doesn't work either.

Answer 3

Last step: \(3x(x+4)+7\); sorry.

Answer 4

I guess prime would be good :)

Answer 5

Okay, thanks!

Answer 6

You are welcome :)
