Factor completely 3x^4 - 3x ^3 - 18x ^2. Which of the following is one of the factors?
Otrada [13]

Answer:

3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).

Step-by-step explanation:

The expression 3x^4 - 3x ^3 - 18x ^2 consists of three terms:

  1. 3x^4;
  2. -3x^3;
  3. -18x^2.

These three terms have common factor 3x^2. Thus,

3x^4 - 3x ^3 - 18x ^2=3x^2(x^2-x-6).

Consider the expression x^2-x-6. You can rewrite it as

x^2-x-6=x^2+2x-3x-6=x(x+2)-3(x+2)=(x+2)(x-3).

The whole expression takes look

3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).

The number of nickels is  (5 + 9) = 14, according to the condition.

Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.

Now you can easily calculate the total and answer the question

   Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50.     ANSWER
