What is the square root method?
The square root method can be used for solving quadratic equations in the form “x² = b.” This method can yield two answers, as the square root of a number can be a negative or a positive number. If an equation can be expressed in this form, it can be solved by finding the square roots of x.

How do you solve for X in a radical equation?
Take the square root of each side of the equation to set up the solution for x x Remove the perfect root factor 2x−1 2 x – 1 under the radical to solve for x x. Simplify the right side of the equation.
How do you solve X²+6x=-2?
For example, solve x²+6x=-2 by manipulating it into (x+3)²=7 and then taking the square root. So far, you’ve either solved quadratic equations by taking the square root or by factoring. These methods are relatively simple and efficient, when applicable.
Why is the square root of the expression added in row?
Adding to in row had the fortunate result of making the expression a perfect square that can be factored as . This allowed us to solve the equation by taking the square root. This was no coincidence, of course. The number was carefully chosen so the resulting expression would be a perfect square.
How do you solve a perfect square with an -term?
Solve . Completing the square on one of the equation’s sides is not helpful if we have an -term on the other side. This is why we subtracted in row , placing all the variable terms on the left-hand side. Furthermore, to complete into a perfect square, we need to add to it.
