Use Completing The Square to put the equation into standard form:
Completing the Square to Solve General Quadratic Equation

Read the vertex point directly from the standard form equation, , which would show k to be the maximum value for your equation. Note carefully, YOUR given equation will have a MAXIMUM, not a minimum.

Find the minimum y-value located on the graph of y= - 3x^2+2x-5.

This graph will have a MAXIMUM (leading coefficient < 0), not a MINIMUM.
Maximum will occur at the x-coordinate of the vertex, or the axis of symmetry, or at: .
When found, substitute this x-value into the equation to get y, the MAXIMUM value.
