1. If 1(-1) for the polynomial f(z) = 2z+z²-5 is-2, can you use the Factor Theorem to find the other factor?

No, because (x+1) is not a factor of the polynomial f(z) = 22 +2²-5,

Yes, because (x + 1) is a factor of all degree 4 polynomials.

No, because-2 is not an irrational number.

Yes, because-2 is the opposite of the leading coefficient of f(z) = 2x¹ +2²-5.
