The polynomial x3 + 8 is equal to

(x + 2)(x2 – 2x + 4).
(x – 2)(x2 + 2x + 4).
(x + 2)(x2 – 2x + 8).
(x – 2)(x2 + 2x + 8).

For this case we have the following polynomial:

We can rewrite this polynomial in the following way:

1) Identify that this binomial is a sum of cubes:

We have then:

2) Factor the binomial as:

Therefore, substituting the values of a and b we have:

Rewriting we have:

The polynomial x ^ 3 + 8 is equal to:

option 1

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
