Question

Need help already got it wrong but I wanna know how to do it for finals.
what is the polynomial function in standard form with zeros 1, 2, 3 and -3?

Answer 1

zeros are the x values that make the polynomial=0, example a polynomial with zeros 1 and 2 is (x-1)(x-2)

Answer 2

oh ok thanks i think i got it now

Answer 3

right

Answer 4

so just to check it would be x^4-3x^3-7x^2+27x-18? or am i wrong?

Answer 5

I think it's +3x^3 and -27x

Answer 6

Kailyn_rae_ is correct:

\[(x - 1)(x - 2)(x -3)(x + 3)\]
\[(x^2 - 3x + 2)(x-3)(x+3)\]
\[(x^2 - 3x + 2)(x^2 - 9)\]
\[x^4 - 9x^2 -3x^3 +27x + 2x^2 - 18\]
\[x^4 -3x^3 - 7x^2 +27x + 18\]
