Solving Quadratic Equations
Step-by-step processes for completing the square and the quadratic formula.
Solving Quadratic Equations
Completing the Square Step 1: isolate variable terms on one side to make a binomial (ax^2 + bx = c).
Completing the Square Step 2: calculate (b / 2)^2.
Completing the Square Step 3: add that calculated value to both sides of the equation.
Completing the Square Step 4: factor the perfect square trinomial on the left into (x - h)^2.
Completing the Square Step 5: take the square root of both sides.
Completing the Square Step 6: solve for x.
Quadratic Formula: x = (-b +/- sqrt(b^2 - 4ac)) / (2a).
