## What value should be added to the expression to create a perfect square? x2 + 16x?

This is math, not programming, but ok.

So a perfect square is an equation that can be written (ax+b)^2. If you actually work out (ax+b)*(ax+b), you find that you get (a^2)x^2 + 2abx + b^2. In x^2+16x, we can see that a^2 = 1 and 2ab = 16. From the first equation, we know that a = 1 (it could also be -1, but you’ll get basically the same answer either way). Using that, the second equation says 2b = 16, or b = 8. The missing value is b^2, or 64.

Which phrase best describes the translation from the graph y = 6×2 to the graph of y = 6(x + 1)2?Now, recall that a solution to any equation occurs when y = 0. Therefore, for a regular quadratic equation, for example 0 = x^2 + 6x + 5, there would be two solutions. Therefore, the perfect square trinomial is #x^2 – 3x + 9/4#. Hopefully this helps!
