What is a square root equation?

Back

A square root equation is an equation that contains a variable within a square root. It can often be solved by isolating the square root and squaring both sides of the equation.

How do you solve a radical equation?

Back

To solve a radical equation, isolate the radical on one side of the equation, square both sides to eliminate the radical, and then solve the resulting equation.

What is an extraneous solution?

Back

An extraneous solution is a solution that emerges from the process of solving an equation but does not satisfy the original equation.

Front

What is the first step in solving the equation √(x) = 5?

Back

The first step is to square both sides of the equation to eliminate the square root, resulting in x = 25.

Front

What are the possible types of solutions for square root equations?

Back

Square root equations can have zero, one, or two solutions, depending on the nature of the equation.

Front

How can you check if a solution is valid for a square root equation?

Back

To check if a solution is valid, substitute the solution back into the original equation to see if it holds true.

Front

What does it mean if a square root equation has two positive solutions?

Back

It means that when the equation is solved, both solutions are greater than zero, indicating that both values satisfy the original equation.

Front

What is the significance of squaring both sides of an equation?

Back

Squaring both sides of an equation is a method used to eliminate square roots, but it can introduce extraneous solutions that must be checked.

Front

What is the solution to the equation √(x + 1) = 6?

Back

The solution is x = 35, found by squaring both sides to get x + 1 = 36, then solving for x.

Front

What is the relationship between square roots and their squares?

Back

The square of a number is the product of the number multiplied by itself, while the square root of a number is a value that, when squared, gives the original number.
