Use the Factor Theorem to find all real zeros for the given polynomial function and one factor. (Enter your answers as a comma-separated list.) f(x) = 5x3 + x2 − 34x + 24; x + 3

Answer 1

by descartes' rule 1 negative zero and 2 positive zeros or 1 - and 2 imaginary, but in this example it's 2+ and 1-

divide x+3 into 5x^3 +x^2 -34x +24 = 5x^2 -14x +8

= (5x-4)(x-2)

zeros are 4/5, 2, and -3

or .8, 2, -3
