What number would you add to make the following expression a perfect trinomial square? Be sure to include the sign. x 2 + 10x _________4. What number would you add to make the following expression a perfect trinomialsquare? Be sure to include the sign. x 2 + 9x _________5. What is the vertex of the graph for the following quadratic function? y = ( x + 2)2 – 36. Use completing the square to find the vertex of the following quadratic function: y = x 2 + 8x + 97. Rewrite the following in transformational (graphing) form using completing the square. The vertex should be easily identified from the equation. y = – x 2 -10X + 17 8.
