How To Solve A Square Root Equation?

How do you find the square root of an equation?

First, we divide both sides by a, since we don’t want a coefficient on x2 gumming up the works.

  1. Then we subtract from both sides to get it out of the way.
  2. Next we take (the coefficient on x), divide by 2, and square to find.
  3. The left-hand side of the equation can now be written as a square:

What are the four steps to solve a square root equation?

Follow the following four steps to solve radical equations.

  • Isolate the radical expression.
  • Square both sides of the equation: If x = y then x2 = y2.
  • Once the radical is removed, solve for the unknown.
  • Check all answers.

What is the square roots 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.
