you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top

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

When cubed and squared are multiplied how do you get your product?

first you get the denominators the same then you multiply the number you multiplied to the denominator to the numerator then you add the two numerators together and keep the denominators the same then if needed you simplify


What do you do when you mutpiling fractions with common dennmonters?

Exactly the same as you do when multiplying fractions with different denominators. -- Multiply numerators . . . the product is the numeratore of the answer. -- Multiply denominators . . . the product is the denominator of the answer.


How do you do multiply fractions?

To multiply a fraction, you multiply the numerators and leave the denominators (assuming the denominators are the same.)e.g. 2/3 x 3/3 = 6/3 or 2If the denominators are not the same, try to find the least common multiple between the two.


How do you add algebraic fractions?

First, you find the greatest common factor of the denominators. Second, you multiply the top by what you had to multiply on the bottom. Finally, you add the numerators together, NOT the denominators they stay the same, and then you would get your answer.


How do you do a Fraction minus a fraction?

If denominators (bottom numbers) are the same,subtract numerators (top numbers).If not you need to make the denominators the same and then subtract numerators.


Will The LCD of two fractions be the same as the LCM of the numerators of the fractions?

No, the LCM of the denominators.


How do you multiply fractions with like denominators?

The numerator and denominator of a product of fractions are simply the products of the numerators and denominators respectively. That is, a/b * c/d = (a*c)/(b*d). The denominators can be the same or different - that is irrelevant.


What is the process of subtracting fractions?

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.


What If the denominator is not the same?

Multiply the denominators to equal numbers, then multiply by the same number for the numerator. Then solve.


Why will the answer always be one when two numerators add up to the same number as two like denominators?

Yes because the numerators add up to equal a whole number which is 1


How do you compare mixed numbers?

First you have to compare the whole numbers. When the whole numbers are the same, compare the fractions. If the denominators of the fraction are the same, compare the numerators. If the denominators are different, convert them to have the least common denominators. Then compare the numerators.


How do you subtract fraction if the if the numerators is the same?

You first have to convert the fractions so that the denominators are the same.
