Complete each quadratic expression so that it is a perfect square. Then write the completed expression in factored form. $$ x^{2}-8 x \square $$
Find the number of solutions to each quadratic equation without actually solving the equation. Explain how you know your answers are correct. $$ x^{2}-2 x-3=0 $$
Solve each equation by completing the square. $$ x^{2}-6 x=-5 $$
Determine whether the points in each set are collinear. Explain how you know. $$ (-2,13),(1.5,-4.5),(3,-12) $$
In Exercises \(5-14\) , determine whether the expression on the left of the equal sign is a difference of squares or a perfect square trinomial. If is, indicate which and then factor the expression and solve the equation for \(x\) . If the expression is in neither form, say so. $$ 49-x^{2}=0 $$
