Front

What does it mean to isolate a variable in an equation?

Back

To manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

What is an extraneous solution?

Back

A solution that is derived from the process of solving an equation but does not satisfy the original equation.
