M E D A L A N D F A N

Answer 1

\[x^{3} - 1 \ is \ cubic \ polynomial, \ \because \ \it \ is\ only \ one \ which \ has \ power \ 3\]

Answer 2

\[3-4i \ will \ be \ another \ solution why, x = \frac{ -b \pm \sqrt{b^{2} - 4ac} }{ 2a }, \ so \ one\ is \ 3 + 4i \ ans \ another \ is 3 - 4i\]

Answer 3

\[x = 3 \pm 4i , \ so \ one \ is \ 3 + 4i \ and \ another \ is \ 3- 4i\]

Answer 4

Last one?

Answer 5

p(x) = (x + 5)(x + 2)x, because it's intersecting x - axis at -5, -2, 0
