if a is a root, then how do you factor the polynomial?

regardless, it's a root of order 3, compare coefficients

@fringe quail

[fringe quail]

(x-a)^3?

[pine kindle]

now expand

[fringe quail]

x^3-a^3-3x^2a+3xa^2

[pine kindle]

and compare

[fringe quail]

d=-a^3

B=3a
C=3a^2

bc=9a^3

bc/9=a^3

d=-bc/9

ohh option in a

[pine kindle]

in all cases you have something divided by 3c, so calculate what 3ac is

[fringe quail]

3ac=9a^3

[pine kindle]

mhm

[fringe quail]

9a^3/3c

-9d/3c

[pine kindle]

seems like none of the above then

[fringe quail]

Ohh no 😭

[pine kindle]

what's the problem

[fringe quail]

I guess we are right

Thanks aL
