Completing the SquareUsed to solve a quadratic equation when factoring will not work
Divide “b” by 2Square that resultAdd to the original equation
How to “complete the square “x2 + bx + ?
Define the factors
Solving x2 + bx = c
Complete the squareAdd the new value to both sidesFactor the left side of the equationFind the square root of both sidesFind the solutions
Solving x2 + bx + c = 0Rewrite the equation as: x2 + bx = cComplete the squareAdd the new value to both sidesFactor the left side of the equationFind the square root of both sidesFind the solutions
Solving ax2 + bx + c = 0
Divide all terms by “a”Rewrite the equation as: ax2 + bx = c
Complete the squareAdd the new value to both sidesFactor the left side of the equationFind the square root of both sidesFind the solutions
