It is important to check your answers to make sure that it doesn't give a zero denominator in the original equation. When we multiply both sides of an equation by the LCM the result might have solutions that are not solutions of the original equation. We have to check possible solutions in the original equation to make sure that the denominator does not equal zero. There is also the possibility that calculation errors were made in solving.

What is the result of solving an equation?
It is the solution of the equation
When solving a rational equation why it is OK to remove the denominator by multiplying both sides by the LCD and why can you not do the same operation when simplifying a rational expression?
You can multiply both sides by the LCD because as a rule, you can do anything to one side of an equation as long as you do the same thing to the other side. But when you simplify a rational EXPRESSION, you don't have an EQUATION. So there is no other side. So you can't multiply both sides by anything. You can, however, multiply both the numerator and the denominator by the same term (except zero).

How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
When solving a rational equation why is it nessecary to perform a check?
to see ifyou made any mistakes
What is the definition of solving a rational equation?
to find the unknown variables
When solving a rational equation what is the first step you must always take?
Get rid of the denominator.
Can the five steps for solving rational equation be eliminated?
no. an individual step might be, but not all.
Can any steps to solving a rational equation be eliminated?
Yes, but it depends on your mathematical skills and confidence.
When solving an algebraic equation which operands do you perform first?
In algebra, you perform the operations inside parentheses first.
What method is used for solving a rational equation?
Methods vary considerably depending upon the number of powers in the equation. For example, the method for solving cubics is quite different to solving quadratics etc... It's not really possible to generalise to one technique.
Is an equation that contains one or more rational expressions?
Yes, an equation that contains one or more rational expressions is called a rational equation. A rational expression is a fraction where the numerator and/or denominator are polynomials. For example, the equation (\frac{x + 1}{x - 2} = 3) is a rational equation because it includes the rational expression (\frac{x + 1}{x - 2}). Solving such equations often involves finding a common denominator and addressing any restrictions on the variable to avoid division by zero.
Can you change any of the steps for solving a rational equation?
Yes. Since "these" do not exist, cjanging them should not make a difference.
How is an extraneous solution of a ration equation similar to an excluded value of a rational equation?
An extraneous solution of a rational equation is a solution that emerges from the algebraic process but does not satisfy the original equation, while an excluded value is a value that makes the denominator zero and is therefore not permissible in the equation. Both concepts highlight the limitations and constraints of rational expressions. Excluded values can lead to extraneous solutions if they are mistakenly included in the solution set. Thus, both are essential to consider when solving rational equations to ensure valid solutions.

Is finding LCD important in solving fractional or rational equation?
Yes, finding the least common denominator (LCD) is crucial in solving fractional or rational equations. The LCD allows you to eliminate the fractions by multiplying all terms by it, simplifying the equation and making it easier to solve. This step helps avoid errors that can arise from working with fractions directly and ensures you can combine like terms efficiently.
