Suppose a classmate missed the lessons on completing the square to find the center and radius of a circle. Explain the process to that classmate. If it helps, use a problem you’ve already done, as an example.
Problem 2
Match each expression with the value needed in the box in order for the expression to be a perfect square trinomial.
Lin says the equation can be solved using the zero product property. Andre says he would complete the square to solve it. Do you agree with either of them? Explain your reasoning.
Use a method of your choice to solve the equation .
