Question

Approximate the real number solutions to the polynomial function f(x) = x3 + 2x2 – 16x – 32 .

x = –4, x = –2, x = 2

x = –2, x = 2, x = 4

x = –4, x = –2, x = 4

x = –4, x = 2, x = 4

Answer 1

factorise it first x3 + 2x2 – 16x – 32 .

Answer 2

can u?

Answer 3

before synthetic division we need one factor.........AND TO get it we use factor theoem
