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 formula p=f/a can be used to relate pressure, force and area. solve the formula for a
Gemiola [76]
<h3>Answer:   a = f/p</h3>

===============================================

Explanation:

We'll solve for 'a' doing these two steps in this exact order

  1. Multiply both sides by 'a'
  2. Divide both sides by p

We do this because we're following PEMDAS in reverse to isolate the variable we want.

The steps look like this

p = f/a

pa = f

a = f/p

Note how ultimately the 'a' and p variables swap places when going from p = f/a to a = f/p
