If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

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

Adding fractions is achieved by adding the numerators as long as the denominators are the same. When the denominators are the same the fractions are "like fractions".

With different denominators they are "unlike fractions"; to be able to add them they need to be converted in to equivalent fractions with the same denominators. They are then "like fractions" and can be added.

To add unlike fractions - fractions with different denominators - you first convert the fractions so they have the same denominator. After that, it's exactly the same as adding fractions which have the same denominator from the start.

Adding unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator .
