Question

equation.

Answer 1

the root of (x-a) is a.
the roots of (x+a)(x+b) are -a , -b
does that help?

Answer 2

Yeah I understand..so am I right when I stated + 4 , - 7 , + 10 , - 12 are the roots of the polynomial equation?

Answer 3

absolutely :)

Answer 4

Im kind of confused on this one :S
Write a polynomial of the smallest degree with roots 1, -3, and 4.
so that means

(x - 1) (x + 3) ( x- 4)?

Answer 5

thats right,u just need to simplify it further...to write it in standard form.

Answer 6

so now its :
(x - 1) (x + 3)

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

(x^3 - 8 + 12)?

Answer 7

i think u missed x there (x^2 + 2 - 3)
it should be (x^2 + 2x - 3)
