Solving Quadratic Equation Given as a Binomial

Reorder the following steps to solve a quadratic equation when the leading coefficient is 1 (a = 1) to solve the equation by completing the square.

• Factor the perfect square trinomial.

• Take the square root of both sides and solve for both cases.

• Write the answer using curly braces in set notation

• Rewrite as

  x² + bx = c

• Take half of b, square it, then

  add this to both sides.
