Question

solve y=x^3-9x determine the intercepts?
how do I solve for x?

Answer 1

you mean solve
\[x^3-9x=0\] for \(x\) ?

Answer 2

yes
i have to find the intercepts

Answer 3

well. other than 0 there are no real roots.

Answer 4

lol
factor as
\[x(x^2-9)=0\] then as
\[x(x+3)(x-3)=0\] and it should be easy from there

Answer 5

ohh ok thanks!

Answer 6

x(x^2+9)

x= 0 X^2+9 = 0

x^2 = -9
x= +-3i

Answer 7

plz give me a medal and close ^^

Answer 8

@zubhanwc3 you misread the question

Answer 9

@satellite73 no i didn't. solving for x means the x intercepts, i told him, 0, 3i and -3i.

Answer 10

take a look at the equation

Answer 11

o.O mb

Answer 12

your rite:P
