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

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

Not true. Try 1/6 + 1/3

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

Only if the problem asks you too

Do you ever have to simplify if you find the LCD when subtracting fractions?

No because in order to subtract or add fractions the denominator of the fractions must be the same and if they are not then the lowest common denominator of the fractions must be found. Having subtracted or added the fractions then it may be possible to simplify the result.

How the LCD of two or more fractions could be of use?

Once you find the LCD, convert the fractions to their equivalents and then you can add and/or subtract them correctly.

What is three eighths plus one fourth?

The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.

Comparing fractions without using an lcd?

It is easy: just convert to decimal fractions.

Why would you want to rename fractions with the LCD?

Possible reasons: To add or subtract fractions, To compare fractions with different denominators.

The lowest common denominator for these fractions and then add and simplify. 23 and 16?

The LCD of 2/3 and 1/6 is 6. 4/6 - 1/6 = 3/6 = 1/2


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.

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 an application of LCD?

Adding fractions. 1/5 + 1/2 need a common denominator to add.
