Consider the graph of the quadratic function y = 2(x + 3)2 – 3 with two real zeros. what number can be added to the right side of the equation to change it to a function with one real zero? .

Making the outside constant on the right be zero will shift the function so the vertex is on the x-axis. At that point, there is only one real zero.

To make that happen, 3 must be added to the -3 that is there.
