Question

Explain, in complete sentences, the difference between a radical equation and an equation simply containing a radical expression. Provide an example of each.

Answer 1

A radical equation has a variable inside a radical.
Equations that have radicals, but not over variables are not radical equations. e.g \[2x=\sqrt{5}\]

Answer 2

I still do not get it....

Answer 3

Here is an example of a radical equation
\[\sqrt{x} = 2\] notice that the x (or variable) is inside the square root.

Here is an example of an equation containing a radical expression
\[x = \sqrt{2}\]
notice that there is a square root here, but the x is not inside it.

Answer 4
