Question

Find all the zeros of each function.
f(x) = x3 - 3x2 + 4x - 12

Answer 1

@timo86m heres my other one

Answer 2

oh nevermind ur here already lol

Answer 3

try factoring

Answer 4

omgeeee....... ohk how do i start?

Answer 5

( ax+b ) (cx^2+ dx+ e ) i guess.

find numbers for a b c d e that will make it look like your equation.

Answer 6

wat?

Answer 7

(x-3)*(x^2+4)

Answer 8

x=3 and use the quadratic formula on (x^2+4) to find other 2

Answer 9

ohk

Answer 10

hold on

Answer 11

2i, -2i?

Answer 12

omg yes :)

Answer 13

ur lying!

Answer 14

yayyy!!!

Answer 15

ohk heres my last one
f(x) = x3 + 2x2 -3x + 20

Answer 16

go ahead and factor lol

Answer 17

(x+4)*(x^2-2*x+5)

pretty much the same way

(x+c) * (x^2+x+d) the best hind is to make c and d = 20

Answer 18

*hint not hind lol

Answer 19

ohk so the first 0 isss???? :)

Answer 20

first zero is (x+4)=0 so x=-4

Answer 21

next use

quadratic formula on (x^2-2*x+5) to find other 2

Answer 22

ohk

Answer 23

1+2i???

Answer 24

yes and 1-2i :) i think they always come in pairs.

Answer 25

yes ohk and the other one is 2?
