Question

Solving radical equations

Answer 1

Let's try to get the radical alone on one side.
First: add 1 to both sides. What do you get then?

Answer 2

4√x = 4
Divide by 4 on both sides to get √x = 1.
Now we have the radical alone. What do we do now?

Answer 3

no clue

Answer 4

We have a square root. To get rid of it, square both sides.
x = 1
That's a simple equation! Now we know that x = 1.
Just to make sure, plug it back into the equation. 4√1 - 1 = 3.
Does that make sense?
