Answer 5

your thoughts on it? were you able to get anywhere?

Answer 6

Separate the polynomial into two groups (each with two terms) and factorize each of them
?

Answer 7

i put D not sure if i got that particular question right but i failed

Shows how D is used for 4 terms polynomials =)

Answer 9

wait so d is the answer? lol

Answer 10

?

Answer 11

Yes. I cannot see how any of the other 'answers' could stand for factoring a 4 terms polynomial.
If the polynomial is a perfect square, then it has to follow \((a + b)^2 = a^2 + 2ab + b^2\)
But that is a 3 terms polynomial.
Even if you'd get the 4 terms by subtraction and addition of squares, by substituting to that form you're not factoring, you get a subtraction or addition.. so it doesn't help factoring.

thank you very much:)
