Graphing Parabola
y = x^2 + 10x + 16

I need to graph this but its not in vertex form. I learned how to put it in vertex form before break but now I've forgotten and my test is tomorrow. Could someone help me put it into vertex form? Thanks

Forgotten ......?

That's why teachers write notes on the board for students to copy down. Have you tried looking at those notes?

$y = (x + 5)^2 - 5^2 + 16 = (x + 5)^2 - 9$.
