Solving radical equations are different because you would want to get everything in the equation to rational numbers.
Extraneous solutions arise when you manipulate the equation. After manipulating if a solution is found that can not satisfy the original equation(s).
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
