I don't like dividing polynomials so I'm going to set x=1 and try them out.

(1-2-14+3)/4 = -3

Of the choices, only D gives -3 when x=1

~~~~~~~~~~~~~~~~~~~~~~

That's as much test-taking as math.  If we were to divide


             x^2 - 5x + 1
          -------------------------------
x + 3 |   x^3 - 2x^2 - 14x + 3
             x^3 + 3x^2
                      -5x^2 - 14x
                       5x^2 + 15x
                                      x + 3 
                                      x + 3

More work, still choice D

Is there a specific rule to follow when dividing simplified fractions? i mean if you were to have the numerator and demoninator
Margaret [11]

Answer:

Step-by-step explanation:

This method consists of multiplying the numerator of the first fraction by the denominator of the second fraction and then writing the answer in the resulting fraction’s numerator.

Next, we multiply the denominator of the first fraction by the numerator of the second fraction, and then write the answer in the resulting fraction’s denominator*.

Lastly, we simplify the final fraction.

For example, in order to divide the fraction

dividing fractions

We multiply the numerator of the first fraction (3) by the denominator of the second fraction (10). This gives us the numerator for the final fraction: 3 x 10 = 30.

Next, we multiply the denominator of the first fraction (4) by the numerator of the second fraction (6). This gives us the denominator of the final fraction: 4 x 6 = 24.

dividing fractions

The last step is to simplify the fraction. Since both numbers are multiples of 6, we can divide the numerator and denominator by 6.

30 ÷ 6 = 5

24 ÷ 6 = 4

Therefore, the result of the division is 5/4.

Method 2 of dividing fractions: Inverting and multiplying

Step 1: Invert the second fraction. That is, swap the numerator for the denominator.

Step 2: Simplify any numerator with any denominator.

Step 3: Multiply across.

For example, we are going to divide:

dividing fractions

Step 1: We invert the second fraction 6/4. This becomes 4/6.

Step 2: We simplify the numerators with the denominators.

Numerators are:

12 = 2 x 2 x 3

4 = 2 × 2

Denominators are:

5 = 5

6 = 2 × 3

We can simplify both from numerator and denominator a 2 and a 3. We call this process “cross canceling” if one numerator has a common factor with the other denominator.

And we multiply across:

The product of nine and a number is added to six the result is 24 what is the number
Andru [333]
Hello!

We can make an equation based on what we know

The product of 9 and a number is

9 * x

Added to six

9 * x + 6

Gives the result of 24

9 * x + 6 = 24

Now you solve it algebraically

Subtract 6 from both sides

9 * x = 18

Divide both sides by 9

x = 2

The answer is 2

Hope this helps!
