Answer 1

3

Answer 2

beacuse it has degree 3... that is, the highest power is 3

Answer 3

in fact that type of equation has exactly 3 roots, no more no less

Answer 4

I amm still confused, is positive real, negative real, or complex zeros?

Answer 5

they are just asking for the number of roots

Answer 6

a polynominal in standard form will always have a number of roots equal to the degree

Answer 7

FYI roots are also known as zeros

Answer 8

well my choices are A: positive real:3or1, Neg real:1, complex:2or 0 B:pos. Real:2 or 0, neg real: 2or 0, complex : 4,2,0 C: pos real: 2or 0. neg real: 0, complex: 2 or 4 and D.: pos real:1, ne 3 or 1, complex: 2 or 0
