solve quadratic equation using completing the square method. Key Strategy in Solving Quadratic Equations using the Square Root Method The general approach is to collect all x2 x2 terms on one side of the equation while keeping the constants to the opposite side. After doing so the next obvious step is to take the square roots of both sides to solve for the value of.

In the given quadratic equation ax 2 bx c 0 divide the complete equation by a coefficient of x 2. In elementary algebra the quadratic formula is a formula that provides the solutions to a quadratic equationThere are other ways of solving a quadratic equation instead of using the quadratic formula such as factoring direct factoring grouping AC method completing the square graphing and others. In these cases we may use other methods for solving a quadratic equation.
To complete the square the leading coefficient latexalatex must equal 1.
This is what is left after taking the square root of both sides. Finally the quadratic formula will work on any quadratic equation. This way we can solve it by isolating the binomial square getting it on one side and taking the square root of each side. If a is not equal to 1 then divide the complete equation by a such that co-efficient of x2 is 1.
