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

Will you give me an example of a radical equation with no solution?

The answer to the question depends on the set of numbers within which you are working. If you are working in integers, x2 = 2.25 has no solution. However, it does have a solution in rational numbers (x = 1.5). If working with rationals, x2 = 6 has no rational solution but it does have a solution in real numbers. Yet again, x2 = -6 has no solution in the reals, but does have a solution in complex numbers.

What does it mean when an equation has no solution?

It means that the equation has no way of working it out / There is no answer.

Why is it the best to use the LCD rather than just any common denominator in adding or subtracting rational expressions?

Using the LCD means you are working with smaller numbers. Also, the answer may require less simplification at the end.

Do you have to have a common denominator when your multiplying?

no u dnt need to have a common denominator.. Just multiply both the denominator and numerator of the fractions u are working on and u will arrive at the answers

How do you make a whole number out of a fraction?

If the numerator divides evenly by the denominator, simply do that. When working with algebra you can multiply both sides by the denominator.

How do you make working model of rational and irrational nos?

Irrational numbers can not be expressed as fractions whereas rational numbers can be expressed as fractions.

How do you work a simultaneous equation?

You cannot work a simultaneous equation. You require a system of equations. How you solve them depends on their nature: two or more linear equations are relatively easy to solve by eliminating variables - one at a time and then substituting these values in the earlier equations. For systems of equations containing non-linear equations it is simpler to substitute for variable expression for one of the variables at the start and working towards the other variable(s).

Does every step in addition and subtraction of different denominators have a mathematical concept involved?

Yes because they must all have the same denominator and this is found by working out their lowest common denominator.

How do you add and subtract rational numbers with unlike denominators?

You first find equivalent fractions whose denominators are a common multiple of the different denominators. Teachers like you to use the least common denominator: that is not necessary although it can result in your working with smaller numbers and so make things easier.

How can a project help your understanding in algebra?

Yes if it involves working out or finding an unknown variable.
