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

How do you minnous fractions?

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45โˆ’25 . Since the denominators are the same, subtract the numerators.


What is the process of subtracting fractions?

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.


Why are two fractions converted into like fractions?

Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.


When you subtract fractions do you subtract the denominator?

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.


How do you add and subtract by fractions?

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.


How would you add or subtract fractions with like denominators?

The same way you would add or subtract whole numbers, leaving the denominators alone.


How do you subtract Fractions with models unlike denominators?

The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.


How do you subtract improper fractions with different denominators?

It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).


How can you use a model to subtract fractions with like denominators?

No. You just have to change it so the denominators are the same, and then it's easy from there!


How do you subtract fractions without alike denominators?

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.


Do you always have to have like numerators in fractions before you can add or subtract?

No, the denominators have to be the same.


Fractions can be added and subtracted only if they're fractions?

We can only add or subtract fractions if they have the same denominators


What are fraction that have same denominator called?

They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.


When do you need a common denominator?

The denominators must be the same before you can add or subtract fractions.


How do you subtract fraction if the if the numerators is the same?

You first have to convert the fractions so that the denominators are the same.


When you add or subtract fractions with the same denominators what happens to the denominator in your answer?

It stays the same. Only the numerators change.


Why are least common denominators important?

In order to subtract or add fractions the denominators must be the same and that's why the LCD must be found.


How do u subtract fractions?

multiply the fractions until they have common denominators and then subtract them


Why do you need a common denominator?

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.


When you add or subtract fractions with unlike denominators why do you have to find LCM?

Because to add fractions, the denominators must be equal.


How do you subtract fractions with unequal denominators?

by finding the common denominator of the fractions


How are lcm's used in adding or subtracting fractions?

To add and subtract fractions, you need common denominators. To find the common denominator, take the LCM of the denominators you wish to add or subtract.


How do you find the difference between two big fractions?

Subtract their numerators providing that they both have the same denominators.


How is finding the LCM revelant when adding and subtracting fractions?

To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.


What are the rules for subtracting fractions?

You multiply the fractions until the denominators are equal. Then, you subtract.
