Why cant dimensional analysis be used to determine if a given equation is correct?
Dimensional analysis simply ensures that two sides of an equation have the same dimensions. By "dimensions" I mean quantities like distance, pressure, force, time, electric charge, etc. For example, a distance can not equal a time. So, if the dimensions are wrong, the equation is wrong, but if the dimensions are right, the equation may be right or it may be wrong. Getting the dimensions right is only part of the task!
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.
How may units to be used to check if an equation is written correctly?
The answer depends on the units of the variables and constants used in the equation.
Three tenths in standard form?
'Standard form' in algebra refers to a way of structuring (phrasing) an equation: Ax+By=C. 'Three tenths' is not an equation, though it may be part of the solution to an equation.
How many roots does a quadratic equation in one variable have?
A quadratic equation has two roots. They may be similar or dissimilar. As the highest power of a quadratic equation is 2 , there are 2 roots. Similarly, in the cubic equation, the highest power is 3, so it has three equal or unequal roots. So the highest power of an equation is the answer to the no of roots of that particular equation.

Where do you go to share a correction to a wrong answer on these pages?
You may correct it yourself. If it might be a matter of opinion, add a correct answer after the incorrect one. But if it's fact and not opinion (someone posted 2+2=67), you may substitute the correct answer instead of the incorrect one. When in doubt, add an answer and don't replace the existing one. To add a correct answer, go to its page and click the "Edit answer" box under the answer.
