Question

State how many imaginary and real zeros the function has.

f(x) = x^3 + 5x^2 - 28x - 32

Answer 1

accidentally closed my last question, any help?

Answer 2

plug x=-1,see if f(-1)=0
if so then x=-1 is a zero of f(x)
2.divide by x+1
or synthetic division by-1

Answer 3

it is a polynomial of degree 3, so there are 3 zeros.

Answer 4

Thank you!!!!
