Answer 2

-3 maybe?

Answer 3

\[7(x-2)^2=7(x-2)(x-2)\]

Answer 4

find the min and that is your answer

Answer 5

well yeah that's the answer and the reason for that if because when we expand like I did you can foil and then we get

\[7(x^2-4x+4)=7x^2-28x+4\]

Answer 6

makes sense ! :))

Answer 7

so if your min is zero and -3 lies below it it cant be part of it.
