When solving a rational equation why is it nessecary to perform a check?
to see ifyou made any mistakes
What do you call the solution of a equation derived from an original equation that is not a solution of the original equation?
That's an extraneous solution. You need to check for these when algebraically solving equations, especially when you take both sides of an equation to a power.
What is a check of a math equation?
I think you are referring to checking a math equation. After you solve an equation you should go back and check your work to make sure you got the right answer. You can do this by plugging your answer back into the equation
How to check the solution to an integer equation?
insert the answer in the equation, replacing the variable, and see if it still makes sense.

How do you check your answer to an equation?
When you are solving an equation usually you are solving for x. If you want to check your answer just plug the values you got back in to the original function. Or you can use a different method to solve the equation and see if you get the same answer.
When solving a rational equation why is it necessary to perform a check?
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.

How does the inverse operation affect solving an equation?
It affects because if you want to solve a multiplication problem you can use it or also to check your division problem
What does it mean to check your answer?
usually used when solving an equation or inequality. Checking one's answer is plugging the answer back in the beginning to make sure you got the correct solution.
What are the steps to solving a radical equation?
Details may vary depending on the equation. Quite often, you have to square both sides of the equation, to get rid of the radical sign. It may be necessary to rearrange the equation before doing this, after doing this, or both. Squaring both sides of the equation may introduce "extraneous" roots (solutions), that is, solutions that are not part of the original equation, so you have to check each solution of the second equation, to see whether it is also a solution of the first equation.
When you find the value of a variable you solve or check an equation?
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
What are the different types of problem solving strategies?
write a math equation , look for a pattern , use a table/ diagram , use logical reasoning guess and check, make a list, daw a picture,
What are the values of x and k when equation of 2x squared plus 5x equals k has equal roots?
If: 2^x2 +5x = k Then: 2x^2 +5x -k = 0 Using and solving the discriminant: k = -3.125 Using and solving the quadratic equation: x = -1.25 Check: 2(-1.25)^2 +5(-1.25) = -3.125
In general when solving a radical equation should you first isolate the radical and then both sides?
It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.
What is true about statements?
Writing a check on an account that does not have the funds to pay the check is illegal. A+
