Two is a zero of the equation x^3−x^2−14x+24=0.
Keith_Richards [23]

Answer:

The factored form is equivalent to the given equation is (x - 2) (x - 3) (x + 4).

Step-by-step explanation:

Since 2 is a zero of the equation x^{3} - x^{2} -14x + 24 = 0

Therefore, (x - 2) is a factor of the equation x^{3} - x^{2} -14x + 24 = 0

Now, on dividing x^{3} - x^{2} -14x + 24 = 0 by (x - 2) we get,

(x - 2) (x^{2} + x - 12) as shown in Fig(1)

On factorising x² + x - 12

= x² + x - 12

=  x² + 4x - 3x - 12

= x (x + 4) - 3 (x + 4)

= (x - 3) (x + 4)

Now, (x - 2) (x^{2} + x - 12) = (x - 2) (x -3) (x + 4)

So the factored form is equivalent to the given equation is (x - 2) (x - 3) (x + 4). Therefore option (c) is the correct answer.

A bag of marbles contains 5 red, 3 blue, 2 green, and 2 yellow marbles. What is the probability that you choose a red marble and
Gwar [14]
The answer will be B.
First you need to find the probability of the red marbles which is 5/12 because there is 5 marbles and if you add they up there would be 12. Then you find the probability of the green marbles which is 2/12. After that you need to multiply them. 5/12 × 2/12. Your answer will be 10/144 but then you can simply by 2. 
 So your answer will be 5/72.
Hope this helped.
