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

Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?

Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).

Difference LCD and LCM?

The function of the numbers in question. The process is the same. When comparing two whole numbers, we call it the LCM. When comparing two fractions, we call it the LCD.

When using the LCD when subtracting fractions do you have to simplify the answer?

Only if the problem asks you too


The LCD of two fractions is the same as the LCM of their denominators.

What is the LCD for fractions?

The LCD for fractions is the LCM (least common multiple) of all of the denominators.

How are the LCM and the LCD different?

LCM can apply to terms which don't look like fractions LCD (denominator) has to be fractions. The LCM of the denominators is the LCD.

Is the LCD of two fractions the same as the LCM of the numerators of the fractions?

The "D" in LCD stands for denominator. The LCD is the same process as the LCM of the denominators.

When is it useful to know multiples of a number?

When reducing fractions to their lowest terms or finding the LCD of fractions

Definition of Multiplying by the least common denominator?

Ordinarily, one finds the least common denominator (LCD) of a set of common fractions in order to add or subtract the set of fractions. The LCD is the least common multiple (LCM) of the denominators of the set of fractions. Without knowing whatis to be multiplied by the LCD, and why, this question is ambiguous.

What is the LCD of 2 4 5?

The LCD, or Lowest Common Denominator, is the smallest multiple of each of the denominators of a set of fractions. So, assuming that 2, 4 and 5 are denominators of fractions (1/2, 1/4 and 1/5, for example), the LCD would be 20, because 20 is the lowest number that 2, 4 and 5 multiply into. So, your new fractions would be 10/20, 5/20 and 4/20. The purpose of finding the LCD is to allow for multiplying fractions together, or simply comparing them easily.

Can you add fractions using the LCD will you never have to simplify the answer?

Not true. Try 1/6 + 1/3

When you add the fractions using the lcd do you have to simplify?

Sometimes you won't be able to, but it's usually a good idea.
