Cancelling out common factors means you are working with smaller numbers. It is usually, but not always, beneficial.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

When multiplying use fraction notification we form products in the numerator and the denominator but do not immediatily calculate the product?

That is correct. It is easier to simplify the fraction before multiplying all the factors in the numerator and the denominator.That is correct.

What is cross canceling in dividing fractions?

Cross canceling is a way to simplify or reduce fractions before multiplying them. For example, 2/4 x 1/6 can be reduced to 1/4 x 1/3 by cross canceling.


Multiplying mixed numbers?

first you turn the mixed number into an improper fraction. then you cross simplify before you multiply. Note: cross-simplifying is pretty much dividing the num. of one fraction by the deno. of the other and then vice-versa. num: =numerator deno. =denominator


Why do you think it is helpful to convert mixed numbers into fractions before multiplying or dividing?

So that you can get your answer more faster and you don't need to do a lot of work


When you multiply fractions why do you multiply the fractions strait across?

This has the effect of producing a denominator in the answer that has each of the original denominators as factors. You don't have to worry about simplifying the fractions before multiplying. Of course, you may have to simplify after multiplying. There's no way out.


Why would you want to factor each expression before multiplying or dividing 2 rational expressions?

In both cases, you may be able to cancel common factors, thus simplifying the expression.


Can you simplify before you divide fractions?

no


What is the the benefit of dividing out greatest common factors before multiplying?

That process helps to simplify your multiplication. If you have a problem such as (27/18)*4, instead of computing 27*4 then dividing that by 18 and simplifying, there is a much easier way to do it. Divide both top and bottom by 9 to get (3/2)*4. Cancel the 2 in the denominator and the 4 that is being multiplied to get 3*2. The resulting answer is 6. Notice how there were no big computations to deal with. This helps especially if you are computing all these numbers by hand or in your head.

Why is it necessary to convert mixed fractions to improper fractions before multiplying or dividing?

Multiplying mixed fractions is very cumbersome and prone to errors. Therefore, it is prudent to convert them to improper fractions. Once that is done, you may simply find the product of all the numerators and divide that by the product of all the denominators. Then you convert back to a mixed number. And there are lots of tricks -- like "canceling out" -- that you can do to simplify the multiplication. Unfortunately, those techniques are very difficult to demonstrate here. It would not be even if it is not an improper fraction and that's why you have to convert


How is multiplying mixed numbers different than multiplying fractions?

if you have mixed numbers you make them into improper fractions before you multiply
