In the last section, we were able to use the Square Root Property to solve the equation \({\left(y-7\right)}^{2}=12\) because the left side was a perfect square. When you complete the square, you change the equation so that the left side of the equation is a perfect square trinomial. Then write the expression as the square of a binomial. ‘Quad’ means four but ‘Quadratic’ means ‘to make square’.
