Undo
To solve an equation it is sometimes helpful to do what to the original operation?

undo the original operation
The resulting equation may not be equivalent to the original equation because raising both sides of an equation to the same power is an operation that introduces extraneous solutions. This can occur when the original equation contains roots or fractional exponents. It's important to verify solutions to ensure they satisfy the original equation.
Extraneous solution
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.

plug your solution back into the original equation and work it out again
x = 00 reduces to x = 0/0. Both are undefined, and thus cannot be considered "equal". Other than that, nothing.
Integration results in an equation which gives the area under the original equation between the bounds. Derivation results in an equation which gives the slope of the original line at any point.
Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.
