How would you simplify #sqrt(2x+3) - sqrt(x+1 )=1#?
1 Answer
You must mean how to solve. I'll solve the equation for you.
Explanation:
Always check the solutions in the original equation to make sure they aren't extraneous. If they do not work in the original equation, you must reject them.
So, x = 3 works. Now, let's check x = -1:
So, x = -1 works as well.
Your solution set would be x = 3, -1
