Radical equations are equations that have square root terms. When solving radical equations, try to isolate the radical expression on one side of the equation and then square both sides (it is the inverse operation of taking a square root). If there are two or more terms on the opposite side of the equation, remember to draw parenthesis around that expression before squaring.
You guys are going to be working on solving radical equations. What that means is that you're going to have a square root and an equal sign. So I'm just going to tell you just one sentence that's going to help you know how to do these.
What you need to do is isolate the square root sign and then square both sides of the equals. If you can remember that, and if that makes sense in your head, you'll be able to do these really well. Let me tell you one more time. What you need to do is undo or isolate anything that's, you're going to isolate the square root by undoing anything that was happening to it like if it was being multiplied by something or divided by something, or adding subtracting whatever. Isolate the square root sign and then square both sides of the equals. From there you solve for x. It sounds pretty easy, you'll see your teacher is going to throw us some tricks at you. You can do it. Just make sure you're being really careful with isolating the square root before you square both sides of the equation.
