you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two

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

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


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.

In fractions, you can NEVER add or subtract


What do you not have to think about when you add or subtract fractions?
