Completing the Square

What is a perfect square trinomial?

Are all trinomials perfect square trinomials?

What do we call the process of adding in a new 'c' value to a binomial to create a perfect square trinomial?

For the binomial $$x^2+bx$$ , what 'c' value should we add to complete the square?

By adding $$\left(\frac{b}{2}\right)^2$$   to the binomial $$x^2+bx$$  , how will the new perfect square trinomial $$x^2+bx+\left(\frac{b}{2}\right)^2$$   factor?

What is the first step to completing the square on the left side of the equation $$x^2+8x-9=0$$  ?

After adding 9 to both sides of the previous equation, we have $$x^2+8x=9$$  . What is the next step to complete the square?

What is $$\left(\frac{b}{2}\right)^2$$   for the equation $$x^2+8x=9$$  ?

After adding 16 to both sides of the equation $$x^2+8x=9$$  , what will the equation look like?

Now that we've completed the square in the equation $$x^2+8x+16=25$$  , what is the next step we should use to solve the equation?
