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).
