Hi,
To find polynomials with the given Zeros, we can write the following monomials and then multiply them together to find the polynomial we want.
First zero is 7 so (x-7)
Second zero is 2 so (x-2)
Third zero is -1 so (x+1)
let's multiply the monomials -> (x-7) * (x-2) * (x+1)
# x^3 + -2x + x + -7x + 14 + -7
# x^3 - 8x + 7 is our polynomial.
I hope this helps, and please reach out if you need additional help :)

Your zeros are correct but final result is lacking the x^2 term. I believe answer S/B x^3 - 8x^2 + 5x +14.05/26/22
