What is the sum of all values of y for which the expression (y + 6)/(y^2 - 4y + 4) is undefined?

For the equation to be undefined, the denominator must equal 0, because anything divided by 0 is undefined.

Thus, we have the equation: \(y^2-4y+4=0\), where we have to solve for y.

To solve for y, use the quadratic formula: \(y = {-b \pm \sqrt{b^2-4ac} \over 2a}\) , because the quadratic is in the form \(ax^2+bx+c=0\)

Can you do it from here?
