Example Question #4672 : Algebra 1

Possible Answers:

Correct answer:

Explanation:








Example Question #18 : Monomials

Multiply:

Possible Answers:

Correct answer:

Explanation:

To multiply this expression, multiply the monomial times both terms in the binomial.

First we will multiply , which represents . This is why we evalute this by multiplying and adding the exponents for x to get .

Now multiply .

Our answer is just .

Example Question #441 : Variables

Multiply  by .

Possible Answers:

Correct answer:

Explanation:

To multiply a monomial by a polynomial, you simply multiply the monomial by each term in the polynomial. In this case that means that the solution is to multiply everything by . The answer becomes .

Example Question #4671 : Algebra 1

Multiply:  

Possible Answers:

Correct answer:

Explanation:

When similar bases are multiplied, their powers can be added.  Distribute the monomial through the polynomial in the parentheses.

The answer is: 

Example Question #4672 : Algebra 1

Simplify:

Possible Answers:

The answers provided do not show the correct simplificaiton. 

Correct answer:

Explanation:

When multiplying a whole number by a polynomial, we simply multiply that number by whatever coefficient is present in front of the variables of the polynomial. We then maintain the variables in the simplified expression.

Example Question #4673 : Algebra 1

Simplify the following expression:

Possible Answers:

Correct answer:

Explanation:

Use the distributive property to multiply the monomial and polynomial.

Example Question #443 : Variables

Evaluate the expression:

Possible Answers:

Correct answer:

Explanation:

Multipying a monomial and trinomial boils down to distributing the monomial amongst all the parts of the trinomial as such:

After some cleanup we get:

Example Question #4676 : Algebra 1

Multiply:

Possible Answers:

Correct answer:

Explanation:

All we need to do here is multiply every term within the polynomial  by the monomial on the outside of the parentheses: .

To do this we need to multiply every term by  and by . Remember that when we multiply by a variable (in this case ), we need to add  to each of the exponents.

So this leaves us with .

Example Question #4677 : Algebra 1

Divide:  

Possible Answers:

Correct answer:

Explanation:

To divide this, we must pull out a common factor from the numerator and denominator.

The common factor from the numerator is only .

The common factor from the denominator is .

The only term that will cancel is the .  We cannot cancel the  inside  and  terms because they are different entities of a quantity.

The answer is:
