Write the polynomial given the roots: 2,-1, and -2

x^3 + x^2 - 4x - 4.

Step-by-step explanation:

In factor form we have:

P(x) = (x - 2)(x + 1)(x + 2)

= (x + 1)(x - 2)(x + 2)

The last 2 factors simplify to the difference of 2 squares

= (x + 1)(x^2 - 4)

= x^3 - 4x + x^2 - 4

= x^3 + x^2 - 4x - 4.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
