**How do you find the vertex of a parabola algebraically and**

For any quadratic equation of the form f(x) = ax 2 +bx+c, the solution is when f(x) = 0. Geometry : The solution is where the graph of a quadratic equation (a parabola) is intersects the x-axis. This, of course, only applies to real solutions. X Advertisement. Example of the quadratic formula to solve an equation. Quadratic Equation: y = x? + 2x + 1, a = 1, b = 2, c = 1. Using the quadratic... Hence use completing the square to solve x2 ?6x =5. c) Use completing the square to solve x 2 ? 5 x +1=0. d) Use completing the square to solve x 2 +8 x +4=0.

- Solve x 2 – 8x + 15 = 0 by using the following graph. The equation they've given me to solve is: 0 = x 2 – 8x + 15. The picture they've given me shows the graph of the related quadratic function: y = x 2 – 8x + 15. The x-intercepts of the graph of the function correspond to where y = 0. The point here is that I need to look at the picture (hoping that the points really do cross at whole
