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

A method used to eliminate radicals from the denominator of a fraction?

That is called "rationalizing the denominator". It consists of multiplying the numerator and the denominator by specific terms, which include square roots. Examples:* If the denominator is root(2) (that is, the square root of 2), multiply numerator and denominator by root(2). * If the denominator is root(2) + root(3), multiply numerator and denominator by root(2) - root(3).

What is the conjugate of a denominator?

This is related to the technique used to eliminate square roots from the denominator. If, for example, the denominator is 4 + root(3), you multiply both numerator and denominator by 4 - root(3). In this case, "4 - root(3)" is said to be the "conjugate" of "4 + root(3)". When doing this, there will be no more square roots in the denominator - but of course, you'll instead have a square root in the numerator.

What are the parts of a fraction?

The numerator, which is the number above the line. The denominator, which is the number below the line. The denominator defines the size of the fractional parts of a whole, and the numerator tells how many there are. A fraction is often used to express the division of the numerator by the denominator.

What is the least common denominator of 15 and 20?

Least common denominator is used for fractions, not integers. Integers can be expressed as fractions, though, by placing them over 1 so if you really meant least common denominator then the answer is 1. If, however, you meant least common multiple, then then answer is 60.

How are divisors and denominators alike?

A fraction represents a decimal number in the form of one number over (or divided by) another. To convert a fraction to a decimal the numerator is divided by the denominator; the denominator is the divisor in this case. A division can be written with the divide symbol (÷) or a solidus (or slash /). The latter is used by most (if not all) computer languages. The solidus is also used to separate the numerator from the denominator of a fraction. The divisor of a division and the denominator of a fraction both occur on the right of the slash in the same place; thus they are the same thing.
