Solving Equations with Radicals

A radical equation is one in which the unknown is under the radical sign (example shown below):

x+1=2

When it comes to solving radical equations, oftentimes teacher will except that you state the domain (or the restrictions). The reason it’s expected because it shows your understanding of the purpose behind solving any equation, that is, when the graph representing the equation crosses the horizontal axis. Sometimes, you may end up getting an answer that doesn’t accurate represent when the graph passes the horizontal axis because it’s outside the domain. Therefore, by stating the restrictions, you know what your boundaries are.
