Hey i was wondering if i could get some help on Algebra.How can i create two radical equations, one that has an extraneous solution, and one that does not have an extraneous solution. Using this as a model; a√x+b+c=d.

Replace a,b,c,d with numbers. Play around with different values until you find a set of numbers that support the solutions you are trying to create. It is a matter of trial and error.

Okay, I think I have it now


Try this:

$$\sqrt{5 - x} - 1 = x$$
