Question

Find all the zeros of the equations below. Please show all work.
x^3-5x^2+6x =0
x^4-8x^2-9=0
x^3-125=0

Answer 1

on the first one, pull an x out and solve as a polynomial to the second power.. third one is a perfect trinomial.

Answer 2

I still have no idea, im not very good with all of this

Answer 3

x(x^2-5x+6) so then that factors into (x-3)(x-2) so the zeros for the first one are 0,3,-2... does that make sense?

Answer 4

yes

Answer 5

how would you solve the second and third problem?
