  5. Completing the Square Process used when transforming a quadratic expression into a perfect square trinomial.

  6. Ex 3 Find the value of c that makes a perfect square trinomial and then factor.

  7. Ex 4 Find the value of c that makes a perfect square trinomial and then factor.

  8. Steps to Solving usingCompleting the Square • If a does not equal one, divide every term by a • Move the constant to the other side. • Take ‘b’, divide by 2 and square it. Add that number to both sides of the equation. • Factor the perfect square trinomial. • Solve by using the Square Root Property. (Don’t forget + and - roots.)
