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

What is compound inequalities?

Compound inequalities are inequalities that have more than one sign, for example, 5


What are some differences between equations and inequalities?

The main difference is that when solving inequalities, if you multiply or divide by a negative number you have to be careful, since you then also have to switch the sign (for example, change a "less-than" sign to a "greater-than" sign). If you multiply or divide by an expression that contains a variable, you have to consider the two cases: that such an expression might be positive, or that it might be negative.


What are all the solution to this system of inequalities. y5x-2 y5x 3?

Since there is no inequality sign, those are not inequalities. An inequality sign is normally one of the following: greater than; less than; great-or-equal; less-than-or-equal.


Are there similarities between an equation and an inequality?

Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.


Why does inequality sign change when both sides are multiplied or divided by a negative number Does this happen with equations why or why not?

I cannot tell you why it changes however it does happen with an equation as most inequalities start off in an equation.


Why can linear equations and linear inequalities be solved the same way?

Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.


What are the two rules for inequalities which do not occur in equations?

Inequalities are not reflexive. Inequalities are not commutative.


Can someone tech me how to do math inequalities please answer as soon as possible.... can you show me how to figure it out?

same way you do equalities, just remember to change the greater or lesser than sign around if you multiply or divide by a negative number.


What is the definition of equivalent inequalities?

The definition of equivalent inequalities: inequalities that have the same set of solutions


Explain how solving inequalities is alike and different from solving equations?

Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").


How do I write a system of linear inequalities?

Instead of using y = mx + b you use y (inequality sign) mx + b. By inequality sign, I mean symbols like
