This study is double blind and the "only spice tea" group serves as the control group.
The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:

The vertex is given by:

In which:
In this problem, the function is given by:
y = 2x² + 25x + 3.
Hence the coefficients are a = 2, b = 25, c = 3, then the coordinates of the vertex are given as follows:
The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).
