Question

The solutions of x^3-6x^2-19x+84=0 are x=-3,4,7
Write the polynomial in factored form

Answer 1

You can find factors by solving each x=i for 0 by subtracting i on both side like x-i=0
or if you have x=-i then x+i=0

Answer 2

So then you could say x-i or x+i are factors

Answer 3

Oh so I should write x-3 etc

Answer 4

x=-3 means x+3=0 not x-3=0
x=-3
add 3 on both sides
x+3=-3+3
x+3=0
so x+3 is a factor

Answer 5

Oh my bad I meant to write x+3
