Best ResponseYou've already chosen the best response.0In the picture, where it says y2^2+6y2+9 in red, I dont know how they are getting the numbers. If I knew where the numbers came from, I could solve it.

Best ResponseYou've already chosen the best response.1\(\begin{align*}(y_2 + 3)^2 &= (y_2 + 3)(y_2 + 3)\\&=y_2(y_2 + 3) + 3(y_2 + 3) \\&= y_2^2 + 3y_2 + 3y_2 + 9 \\&=y_2^2 + 6y_2 + 9\end{align*}\)
