Question

What is a polynomial function in standard form with zeroes 1, 2, –3, and –3?

g(x) = x^4 + 3x^3 –7x^2 – 15x + 18
g(x) = x^4 + 3x^3 – 7x^2 + 2x + 18
g(x) = x^4 – 3x^3 + 7x^2 + 15x + 18
g(x) = x^4 – 3x^3 – 7x^2 + 15x + 18

hope you found your answer

Answer 8

plug in the roots and you should get the equation being zero. since you have 1 in the list, there is nothing easier to start with. plug 1 in the equation and you'll end up with zero. In case of other equations, they won't become zero.

Answer 9

you can also test the roots by descarte's rule of signs.
