Example Question #3 : Simplifying Expressions

Expand:

 

Possible Answers:

Correct answer:

Explanation:

To expand, multiply 8x by both terms in the expression (3x + 7).

8x multiplied by 3x is 24x².

8x multiplied by 7 is 56x.

Therefore, 8x(3x + 7) = 24x² + 56x.

Example Question #4 : Simplifying Expressions

Simplify:

Possible Answers:

None of the other answers are correct.

Correct answer:

Explanation:

First, distribute –5 through the parentheses by multiplying both terms by –5.

Then, combine the like-termed variables (–5x and –3x).

Example Question #1 : How To Add Polynomials

Simplify the expression.

Possible Answers:

None of the other answers are correct.

Correct answer:

Explanation:

When simplifying polynomials, only combine the variables with like terms.

can be added to , giving

can be subtracted from  to give .

Combine both of the terms into one expression to find the answer:

Example Question #1 : How To Add Polynomials

Simplify the following expression.

Possible Answers:

Correct answer:

Explanation:

This is not a FOIL problem, as we are adding rather than multiplying the terms in parentheses.

Add like terms to solve.

 and  have no like terms and cannot be combined with anything.

5 and -5 can be combined however:

This leaves us with .

Example Question #1942 : Algebra Ii

Simplify the following expression:

Possible Answers:

Correct answer:

Explanation:

This is not a FOIL problem, as we are adding rather than multiplying the terms in parentheses.

Add like terms together:

has no like terms.

Combine these terms into one expression to find the answer:

Example Question #1943 : Algebra Ii

Simplify the expression.

Possible Answers:

The expression cannot be simplified further.

Correct answer:

Explanation:

When multiplying exponential components, you must add the powers of each term together.

Example Question #1944 : Algebra Ii

Possible Answers:

None of the other answers are correct.

Correct answer:

Explanation:

When multiplying polynomials, add the powers of each like-termed variable together.

For x: 5 + 2 = 7

For y: 17 + 2 = 19

Therefore the answer is .

Example Question #1945 : Algebra Ii

Simplify the following:

Possible Answers:

This fraction cannot be simplified.

Correct answer:

Explanation:

First we will factor the numerator:

Then factor the denominator:

We can re-write the original fraction with these factors and then cancel an (x-5) term from both parts:
