Example Question #31 : Simplifying Polynomials

Write the polynomial in standard form that has zeroes at 3, and .

Possible Answers:

Correct answer:

Explanation:

From the zeroes we know:

First use FOIL method to simplify terms containing irrational numbers:

Which simplifies to:

FOIL again:

Example Question #35 : Intermediate Single Variable Algebra

Simplify .

Possible Answers:

Correct answer:

Explanation:

We can start by factoring a  out of the numerator and denominator and cancel them:

Then we can factor the quadratic that's left in the denominator and cancel the one of the terms with the term in the numerator:

 

Example Question #37 : Simplifying Polynomials

If  and , simplify .

Possible Answers:

Correct answer:

Explanation:

We should start by writing everything out so we can have a good look at it:

To factor the numerator, let's group the first two and the last two terms:

We can factor out a  from the first group in the numerator, and a  from the second group:

Now we can factor out the  from both terms in the numerator:

We can then cancel the  from the numerator and the denominator, leaving us with a final answer of:

Example Question #32 : Simplifying Polynomials

Simplify the polynomial:

Possible Answers:

Correct answer:

Explanation:

To simplify the polynomial expression, we can simplify each term individually. To start, the first term has a difference of squares in the numerator, which can be rewritten as 

using the formula

We can now simplify the first term completely to .

The second term can now be simplified:

Note that one could also simplify the denominator by itself by finding the least common denominator, and then simplify the entire term.

Now that all the terms are simplified, our final answer is

Example Question #1172 : Algebra Ii

Simplify:

Possible Answers:

Correct answer:

Explanation:

To simplify this expression, identify what goes into every one of the terms.

In this case, it's -7.

Then, take that out from each of the terms, remembering to pay attention to the signs.

Therefore, your answer is:

.

Example Question #1173 : Algebra Ii

Simplify:

Possible Answers:

Correct answer:

Explanation:

First, distribute the -1 at the front of the second expression:

.

Then, combine like terms to get your answer of

Example Question #1174 : Algebra Ii

Simplify:

Possible Answers:

Correct answer:

Explanation:

To simplify, first remember to distribute the negative sign in front of the second set of terms:

.

Then, combine like terms.

Your answer is:

.

Example Question #1175 : Algebra Ii

Simplify:

Possible Answers:

Correct answer:

Explanation:

To simplify this expression, first identify the greatest common factor for this set of terms.

In this case, it's 4.

Then, factor 4 out of each of the terms to get your answer of:
