How to multiply polynomials in pre-algebra - Math

First you look at the . Nine is a perfect square, meaning . Because the negative sign is outside the radical, you add it in at the end of the problem, after = . Therefore, the answer is .

First you multiply the coefficients and . Then you use the rules of exponents to add the exponents because you are multiplying the bases. This becomes . You then combine the two parts to equal .

Multiply using the FOIL method.

In order to simplify this problem distribute to each component of .

Distribute.

Multiply and simplify.

When multiplying polynomials you add the powers of each like-termed polynomial together to find the answer.

In this example the powers are and which add to .

Therefore our answer is .

When multiplying polynomials you add the powers of each like-termed polynomial together to find the answer.

In this example the powers are and which add to .

Therefore our answer is

To simplify, we need to multiply all terms together. It is easiest to re-order the expression and group like terms together.

Now we can simplify.

When multiplying polynomials you add the powers of each like-termed polynomial together so we add the powers of each like-termed variable to find the answer.

In this example the exponents are and so

Our answer is .

When multiplying polynomials, add the powers of each like termed polynomial together to find the answer.

In this example the variables are , and so

Our answer is .

When multiplying monomials with the same base, you simply add the exponents together.

In this example the monomials are , , and so .

Our answer is .

Solve using the FOIL method. Don't forget to include the negative sign!

First:

Outside:

Inside:

Last:

Add together, and combine like terms.

When multiplying variables, you add the exponents of each like-termed variable together to find the answer.

In this example, the exponents are and so .

Our answer is .

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

In this example the variables are raised to the and so will be the power of in our answer.

Then we multiply the numbers in front of our variables to get .

Combine the number and our new variable to get the answer .

Multiply to get a common denominator:

Next, using FOIL (first, outer, inner, last) remove the parantheses and then combine like terms to get:

Use the distributive property:

If the width is , then the length is . The perimeter equals , so .

solving for , we have

, the width, so the length is .

Then, to find the area we multiply times , which equals .

Convert % to a decimal, which is .

Then multiply by to get .

First you look at the . Nine is a perfect square, meaning . Because the negative sign is outside the radical, you add it in at the end of the problem, after = . Therefore, the answer is .
