### Example Question #7 : Adding And Subtracting Rational Expressions

Subtract:

Explanation:

First let us find a common denominator as follows:

Now we can subtract the numerators which gives us :

### Example Question #4314 : Algebra 1

Simplify:

None of the above

Explanation:

Factor both the numerator and the denominator which gives us the following:

After cancelling we get

### Example Question #6 : Multiplication And Division

Simplify the following:

Explanation:

We are dividing the polynomial by a monomial. In essence, we are dividing each term of the polynomial by the monomial. First I like to re-write this expression as a fraction. So,

So now we see the three terms to be divided on top. We will divide each term by the monomial on the bottom. To show this better, we can rewrite the equation.

Now we must remember the rule for dividing variable exponents. The rule is So, we can use this rule and apply it to our expression above. Then,

### Example Question #2 : Dividing Polynomials

Divide:

Explanation:

First, rewrite this problem so that the missing  term is replaced by

, the first term of the quotient

Multiply this term by the divisor, and subtract the product from the dividend:

Repeat this process with each difference:

, the second term of the quotient

One more time:

, the third term of the quotient

, the remainder

The quotient is  and the remainder is ; this can be rewritten as a quotient of

### Example Question #21 : Polynomial Operations

Divide:

Explanation:

Divide the leading coefficients to get the first term of the quotient:

, the first term of the quotient

Multiply this term by the divisor, and subtract the product from the dividend:

Repeat these steps with the differences until the difference is an integer. As it turns out, we need to repeat only once:

, the second term of the quotient

, the remainder

Putting it all together, the quotient can be written as .

### Example Question #4315 : Algebra 1

Divide the polynomials:

Explanation:

In order to divide these polynomials, we will need to factorize both the top and the bottom expressions.

Cancel out the common terms in the numerator and denominator.

### Example Question #81 : Polynomials

Divide the polynomials  and .

Explanation:

Write an expression to divide the polynomials.

Both polynomials can be factorized.

The numerator will be simplified to .

The denominator cannot be factorized as is.  Pull a common factor of two in the denominator.

The  term can be factorized to .

We can now rewrite the fraction.

The common  terms in the numerator and denominator can be cancelled.

Distribute the two in the denominator through both terms in the binomial.
